حل كتاب المدرسة ماث للصف الثالث الابتدائى حل كتاب المدرسة ماث للصف الثالث الابتدائى من الدرس 41 الى 50 Directions: For each shape below, do the following:• Measure and record each of the side lengths of the quadrilaterals with your ruler.• Label the units.LESSON 41: APPLY Directions: Refl ect on your learning about perimeter. Think about how you found the perimeter of the shapes today. Why is perimeter a linear measurement? Write your thoughts in the box below.LESSON 41: MATH JOURNAL Directions: Look at the shapes below. Circle the shapes that are polygons and cross out the shapes that are NOT polygons.LESSON 42: CONNECT Directions: 1. Choose two polygons from the Connect page and carefully cut them out.2. Glue the two shapes below.3. Write the name of each polygon on the lines below.4. Measure and record the length of each side of Polygon 1. Be sure to label your measurements.5. Find the total perimeter of Polygon 1 and record it on the chart on the next page.6. Repeat steps 4 and 5 for Polygon 2.7. Find the diff erence between the perimeters of the two polygons. Show your work.LESSON 42: APPLY Directions: Follow the directions below.LESSON 43: APPLY Write the names of the shapes in order from smallest ACTUAL perimeter to greatest ACTUAL perimeter. Directions: Work with your Shoulder Partner to solve the perimeter and area problems below. Your teacher will give you additional directions.LESSON 44: APPLY 1. How much fencing would you need to make ALL of these pens?2. How many square meters of space would the animals have if you combined ALL Directions: How would you explain the diff erence between perimeter and area to a Primary 2 student? Write your explanation in the box below. Use numbers, pictures, and words to explain the diff erence.LESSON 44: MATH JOURNAL Directions: Look at the space requirements for the animals below. Then determine which pen each animal could use. Write the area of the pen and the name of the animal for each pen. Some pens might work for multiple animals.LESSON 45: APPLY Directions: A friend said that the area of the square shown below is 8 square units. Do you agree or disagree? Explain your thinking in the box below using words, pictures, and/or numbers. Directions: Choose two of the problems below to demonstrate strategies for fi nding the area of rectangles. For each problem, show TWO ways to fi nd the area. Explain your thinking using words, pictures, and/or numbers. Remember to label all of your answers. Directions: Use counters to solve the division problems below. For each problem, draw a picture to show your solution. Walid invited his friends over to play board games. He has 24 small square tables that he wants to arrange to make a larger rectangular table.LESSON 47: APPLYPart 1 Directions: In the grid below, draw as many rectangular tables as you can. Label the width and length and then write an equation to fi nd the area and another equation to fi nd the perimeter. One rectangular table is done for you. Do two rectangles with the same area always have the same perimeter? Directions: Complete the following steps.1. Use your ruler to draw two diff erent rectangles with an area of 6 square cm. 2. Label the side lengths of each rectangle.3. Calculate the perimeter of each rectangle.4. Compare the two perimeters and explain your observations using words and/or numbers. LESSON 48: CONNECT Directions: Complete the following steps.1. In the space below, use your ruler to draw two diff erent rectangles with a perimeter of 20 cm. 2. Label the side lengths of each rectangle.3. Calculate the area of each rectangle.4. Compare the two areas and explain your observations using words and/or numbers. LESSON 48: APPLY Refl ect on your learning about area and perimeter. In the box below, explain the strategy you used to solve today’s Apply problem. You may use words, numbers, and/or pictures.LESSON 48: MATH JOURNAL Directions: Use counters to solve the division problems below. For each problem draw a picture to show your solution.LESSON 49: CONNECTPart 1 Directions: Solve the story problems below. Include a drawing and an equation for each problem. Be sure to label your answers. LESSON 49: APPLY1. Shaimaa is sewing a border on a square baby blanket. The length of the blanket is 45 centimeters and the width is 45 centimeters. How long will the border be? Directions: Draw lines to represent the groups of 10 to help you solve the following problems.LESSON 50: APPLY
