Use any of the models to demonstrate the division of a fraction by another fraction.do two examples.

Use the cut-out strips to determine 2÷3.

1. What is 2 times 4? will the answer be bigger or smaller than 4? Explain your answer.
2.what is half of 4? Will the answer be bigger or smaller than 4? explain your answer.
3.what is half of the answer you got in no. 2?will the answer be bigger or smaller than the answer you got in no.2?
4. What is half of the answer you got in no.3? Will the answer be bigger or smaller than the answer you got in no.3?what do you notice by considering your answer no.'s 1 to 4? elaborate.

Use the variety of figures(triangles, squares,etc)to represent and determine the difference between the following fractions:
1. 1/3-1/5.
2. 1/2-3/8.
3. 2/5-1/4.

The left and right page numbers of an open book are two consecutive integers whose sum is 419. Find the page numbers

3(2x + 11) = 9 Reason for each step

6x + 33 = 9 Reason for each step

6x=-24 reason for each step

X=-4 reason for each step


44 - 2(3x + 4) = -18x Reason for each step


44 - 6x - 8 = -18x Reason for each step

-6x + 36 = -18x Reason for each step

36 = -12x Reason for each step


-3 = x Reason for each step

1. Which of the following shapes would you use to teach fractions?provide reasons for each shape.
1.1. octagon

1.3. square
1.4. sphere
1.5. trapezoid
1.6. rectangle
1.7.pentagon
1.8.triangle
1.9. cylinder
1.10.cube

Write an equivalent fraction for:
a. 1/4.
b. 1/2.
c. 6/8.
d. 2/4.
e. 2/2.
f. 2/8.
g. 8/8.
h. 4/8.
i. 4/4.

1. Draw a fraction wall that has fifths,tenths,thirds and twelfths.
2.use the number line to illustrate the equivalence of 2/3 and 4/6.
3. Use the same number line to illustrate the equivalence of 3/4 and 9/12.

1. Define fraction.
2.draw four different diagrams, which can be used to show wholes that are divided into three parts, but which do not all represent thirds.
