Character Principle
Hardwork “All hard work brings a profit, but mere talk leads only to poverty.” Proverbs 14:23
LESSON PRESENTATION
Pre-test
Assign two problems to each student to review their knowledge on percent equivalent and decimal numbers.
Set The teacher will distribute a hand out, a paper, a pencil and an erasor to each student.
The hand out cantains examples and diagrams that will capture students attention hence make them understand easily.
Teacher Instruction and Modeling
The teacher will exlain to students how to convert decimals into percentage equivalent i.e. by multiplying a decimal number by 100.
The teacher will demonstrate how to convert decimals into percentage equivalent using two examples.
i.e. 0.50 x 100 = 50%
0.10 x 100 = 10%
The teacher will give two problems for each student to solve and review the questions together with the students.
When the students properly understands how to convert decimals into percentages, the teacher will introduce conversion of percentage to decimal numbers. The teacher will explain that this is done by dividing the percent with a 100 and demonstrate using the examples above
i.e. 50% = 50/100 = 0.50
10% = 10/100 = 0.10
Then he will give two problems for stuents to practice then review the question together with the students.
Guided Student Practice
The teacher will give more problems to the students to solve while monitoring the progress and assisting the weaker students. The Teacher will give candies to students who gets the problems right.
Independent Student Practice
Once the teacher is convinced that the students have understood the concept properly and are able to convert decimals into percent equivaslent and pecent equivalent to decimals, he will assign more 10 questions for indidual practice.
5 out of the 10 questions will test conversion of decimals to percent equivalent while 5 will test conversion of percent to decimals.
Closure
The teacher will end the lesson by saying, “Today we learnt about conversion of decimals into percent equivalents and percent to decimals”. Then he wil ask the students to explain the process to him.
The teacher will then give a candy to each and every student in the class and remind them that next time he will only give candies to students who get all the questions right.
Summative Assessment
As the students are doing the 10 questions, the teacher will move around the class evaluating each student’s understanding of the concept. He will review the concept with students who have not understood properly and arrange for further coaching.
LESSON REFLECTION
Describe the outcome of the lesson.
Students’ understanding of the topic was satisfactory. The students were participative in class and were very enthusiastic to get the candies. This was a good motivation.
Describe student performance and state the number of students who achieved the objective.
Out of the 20 students in the class, 17 students met the lesson objective i.e. they were able to solve 8 out of 10 questions correctly. However, 3 students performed below expectation with two scoring 7/10 and the third one scoring 6/10.
Describe an alternative approach for this lesson.
Use of more interactive website such as http://www.aaamath.com would help the 3 student understand the concept properly. Extra coaching time should be allocated to ensure the 3 students properly understand the concept.
Describe an appropriate lesson to follow this lesson.
The next lesson will be conversion of conversion of reccuring decimals into fractions.
Analysis essay:
Hard outs and charts were very useful tools for teaching decimals and percentages. After introducing the topic, the students had some difficulties compreheading how to convert decimals into percentage and vice versa. By just using numbers and doing some examples on the chalk board, some students could not clearly comprehend the concept. The hard out came in hardy as it explained concept in word while the chart gave examples that were also explained in words. The chart explained simple problems first then progressed to complex ones thereby enhancing the flow of the lesson. In addition to just having problem written in numbers, the chart explained the numbers in words which made it easier for students to understand.
Example of an explanation from the chart;
0.50 x 100 = 50%
0.50 is equivalent to 50%.
0.50 is equivalent to a half of something. 50% is also equivalent to a half of something. Therefore, 0.50 is the same as 50%.
To convert 0.50 into percentage, you multiply it by 100 to give you 50
i.e. 0.50 x 100 = 50
since we are converting decimals into percentage, then you just add a percent sign at the end to make it percentage
i.e. 0.50 x 100 = 50%

The chart had the same explanation for converting percentages into decimals. This made it very easy for students to understand.
To make the concept well understood, I showed the student a complete fraction circle. Then I devided the circle into two halves. Since the students had a clear understanding of fractions, I explained to them that the each half of the cirlcle is equivalent to 0.50 or 50% of the full circle. This further enhanced students’ understanding of the concept.
In addition, the candies worked out the magic. Every student wanted the candies. Therefore, they paid extra attention to the lesson in order to grab the concept and solve the problems correctly thus get the candies. This experience was very different from previous lessons when there is nothing to motivate the students.
The hard outs and the charts are effective tools for teaching conversion of decimals into percetanges and vise versa. Candies also motivated the student which enhanced easy understanding ot the concept.
The materials were easy to use, straight foraward and very applicable. However, the lesson can be improved and made more interesting by introduction of teaching materials that simulate a play e.g. a computer game. Read More

Equivalence/fractions

...Teaching Equivalent Fractions There are a number of prerequisite skills that should have before proceeding to learn about equivalent fractions. Three of these prerequisite skills include knowing how to multiply and divide, an understanding of factors, and an introduction to fractions (including such vocabulary as numerator and denominator. (TeacherVision, 2008). Manipulatives can and should be used to introduce the concept of equivalent fractions. One such manipulative involves folding a rectangular piece of paper into three, equal squares. Have students shade in two of the three squares, and ask them what fraction this represents – two thirds. Next, have students fold the same piece of paper in half horizontally to create six...

Math - Fractions

D e v e l o p i n g M a t h e m a t i c s A p p r o a c h Toward Effective Learning A calling that offers the opportunity to mold so many young lives, that we call teaching. It is a mission that can sometimes be overwhelming. When teaching becomes a little challenging than usual, we turn to programs and perspectives that are intended for children with special needs.
Visual Learning. Everyone has a left brain and a right brain and we all use both sides. But most of us use one side more than the other, this is called hemispheric dominance. The left side of the brain processes linear information: science & analysis, language, reading, math & logic and writing (Sobanski, 2002, p.3). The right side on the other hand processes holist...

Math and the paraprofessional teaching fractions

...Maths and the paraprofessional teaching fraction xxxxx School: xxxxx xxxxx xxxxx Due xxxxxx Introduction In fractions, models are used because of a number of reasons. However, the most important is that it helps to give the concept of fraction as a number (Department of Education and Early Childhood Development, 2009). Different models are used to make a clear understanding of the concept among the students. As few young ones are unable to grasp a certain concept or idea, therefore through other means, the concept can be embedded in their minds in a better way. Hence, they can have a long-term understanding of fractions. In order to develop deep understanding of fractions, there are some concrete examples to the three fraction models...

Phase 2 Individual Project

...Phase 2 Individual Project Business According to the Bureau of Labor Statistics, the unemployment rate for the of Georgia for September was 9.0 percent. As a decimal, this rate would be written as 0.09. The calculation used to come to this figure was 9.0 divided by 100. As a reduced fraction, the unemployment rate would be expressed as 9/100. This is because the fraction cannot be reduced any further without using decimals and not whole numbers. If there were 390,000 individuals who could work, then 35,100 individuals would be unemployed. The equation used to figure this out is 0.09 * 390,000.

Change Management

...Introduction Change is an aspect that cannot be ignored in any given organisation yet the human instinct naturally opposes change. Change usually occurs frequently and at a rapid pace. Consequently, those who tend to resist it may slow down an organisation or even destroy it altogether. Resistance to change usually occurs as a result of the natural tendency to maintain status quo. Human beings generally have an inclination towards stability and this means that organizational change may be regarded as something that will cause instability. Usually, employees may begin depicting some signs of resistance through scepticism. This kind of behaviour creates a barrier that may make it extremely hard to implement organisational change...

A Hydrograph of River Cynon and Design of an Open Channel

... of rainfall (1.2 mm at 00:00:00 on October 12) to the peak river height (0.658 m[BV] m3/hr at 09:00:00 on October 14) during the four-day observation, 22 hours elapsed. This is the basin lag time. The rising limb starts during the first peak of the rainfall and culminates with peak river height. As shown in Figure 2, the rising limb is steep. This phenomenon indicates a slower infiltration rate and larger overland flow. Slow infiltration rates may, in turn be attributed to the hydrogeology of the catchment area. Much of this catchment has moderate permeability (65.5 percent inter-granular and 5.8 percent fissured) and, therefore, slow infiltration (British Geological Society, 2005). The catchment area is comparatively large at 160 square...

The Functions of Modern Central Banking

It now directs and supervises banking activities through a complex set of tools and instruments that embody the country’s monetary policies.
Central banking can be traced to the 17th century Swedish Riksbank. The bank was created in 1668 as a joint-stock bank and helped the Swedish government with its monetary needs as well as serve as a clearinghouse for commerce. Just a few decades after, or in 1694, England established its own joint-stock bank called Bank of England. It was established primarily to buy the country’s debts. Other European countries soon followed and established their own national banks not only to serve their debts but also to solve monetary disarray as in the case of France’s Banque de Fr...
