Here are the solutions for the math problems on your worksheet.
Wednesday
1. Write the equivalent fraction.
* Look at the first bar: It is split into 3 parts, and 1 is shaded ($\frac{1}{3}$).
* Look at the second bar below it: It has the same length but is split into 6 smaller parts. The shaded part covers 2 of those small parts.
* So, $\frac{1}{3}$ is equal to $\frac{2}{6}$.
*
Answer: $\frac{2}{6}$
2. Find the perimeter.
* Perimeter is the distance around the outside of the shape. Add up all four sides.
* Top side = 3 in., Bottom side = 3 in.
* Left side = 2 in., Right side = 2 in.
* $3 + 3 + 2 + 2 = 10$
*
Answer: $p = 10 \text{ in.}$
3. Shade in the rectangles.
* A rectangle is a shape with 4 straight sides and 4 square corners (like a box or a door).
*
Shade these shapes:
* The top-left shape (horizontal box).
* The tall vertical shape in the middle.
* The tilted shape on the far right.
*
Do NOT shade: The diamond (rhombus) or the slanted parallelogram on the bottom left, because their corners are not square.
4. Sam has 15 apples.
* Sam puts an equal number of apples on 3 plates. This is a division problem.
* $15 \div 3 = 5$
*
Model: Draw 3 circles (plates). Put 5 dots (apples) inside each circle.
*
Answer: 5 apples on each plate.
5. Find the area.
* Area is the space inside the shape. We can split this "L" shape into two rectangles to make it easier.
*
Rectangle 1 (Left side): It is 8 inches tall and 4 inches wide.
* $8 \times 4 = 32 \text{ sq in.}$
*
Rectangle 2 (Right side sticking out): The total width at the bottom is 8 inches. The left part is 4 inches wide, so the right part is $8 - 4 = 4$ inches wide. The height of this part is 4 inches.
* $4 \times 4 = 16 \text{ sq in.}$
*
Total Area: Add them together: $32 + 16 = 48$.
*
Answer: $48 \text{ sq in.}$

Thursday
Eye Colors of the Class (Bar Graph)
1. How many students have hazel eyes?
* Find the bar labeled "Hazel."
* Follow the bar to the right. It ends halfway between 4 and 6.
*
Answer: 5 students
2. How many more students have blue eyes than brown?
* Blue eyes bar goes to 12.
* Brown eyes bar goes to 8.
* Subtract: $12 - 8 = 4$.
*
Answer: 4 more students
3. How many fewer students have green eyes than brown?
* Green eyes bar goes to 3 (halfway between 2 and 4).
* Brown eyes bar goes to 8.
* Subtract: $8 - 3 = 5$.
*
Answer: 5 fewer students
4. Ally has 7 grapes.
* She eats 2: $7 - 2 = 5$
* She gives 3 away: $5 - 3 = 2$
*
Fill in the blanks:
* $7 - 2 = \mathbf{5}$
* $5 - 3 = \mathbf{2}$
* $g = \mathbf{2}$
* She has
2 grapes left.
5. Compare the fractions.
* Look at the pictures. The top picture shows $\frac{1}{2}$ (one big piece). The bottom picture shows $\frac{1}{4}$ (one small piece).
* Visually, the shaded part for $\frac{1}{2}$ is much larger than the shaded part for $\frac{1}{4}$.
*
Answer: $\frac{1}{2} > \frac{1}{4}$ (Use the greater than symbol: $>$)
