I-Ready At-Home Math Grade 7 Lesson 6 - Use Circle Vocabulary

Oct 1, 2026

At-Home Math center activity for Grade 7 Lesson 6 focuses on using circle vocabulary to solve measurement problems. Students read a problem, consider solution steps, then fill blanks using words and numbers from word and number banks exactly once, collaborating by taking turns. They check whether descriptions match a circular sandbox and revise mistakes. A further prompt uses word-bank terms to connect radius, diameter, circumference, and area for a pizza.

CENTER ACTIVITY Names: LESSON 6 Use Circle Vocabulary What You Need • Recording Sheet What You Do 1 Read the problem on the Recording Sheet. Think about how to solve it. KEEP IN MIND You may change your mind after you fill in some of the blanks. It’s okay to erase. 2 Read the paragraphs that tell how to solve the problem. 3 Use the words and numbers from the word bank and the number bank to fill in the blanks. You can use each word or number only once. You will not use all the words or numbers. 4 Take turns. After you fill in a blank, the next group member fills in the next one. 5 When all the blanks are filled, read the paragraphs aloud. Do they make sense? 6 Fix any mistakes if you need to. Check Understanding ~~ ~~ The diagram shows a plan for a circular sandbox. Use circle vocabulary to describe the size of the 5 ft sandbox in three different ways. Go Further ~~ ~~ Use as many words as you can from the word bank to describe what the radius, diameter, circumference, and area of a pizza tell you about that pizza. ©Curriculum Associates, LLC Copying permitted for classroom use. GRADE 7 LESSON 6 Page 1 of 2 CENTER ACTIVITY Names: LESSON 6 Use Circle Vocabulary RECORDING SHEET Joe’s Café sells two different-sized pizzas, as shown. How much bigger is the large pizza? The shape of each pizza is a(n) . There are different ways to measure the size of a circle. You can find its , or the distance across a circle through its center. You can find its , or the distance around the circle. You can also find its , or the amount of space inside the circle. Mary decides to calculate the area of each pizza to compare their sizes. She uses the formula . In this formula, the symbol p represents a constant called . It is the ratio of the circumference to the diameter of any circle and has an approximate value of . The variable r represents the , which is the distance from the of a circle to any point on the circle. The value of r for the small pizza is inches, and for the large pizza it is inches. The approximate area of the small pizza is in.2. For the large pizza it is in.2. This means that the large pizza is approximately in.2 bigger than the small pizza.

GRADE 7 LESSON 6 Page 2 of 2 CENTER ACTIVITY Name: LESSON 25 Match Prisms with Surface Area What You Need • Surface Area Formula Cards • Surface Area Cards • Prism Cards What You Do 1 Shuffle the Surface Area Formula Cards and place them faceup in rows on one side of the table. 2 Shuffle the Surface Area Cards and place them faceup in rowson the other side of the table. 3 Shuffle the Prism Cards and place them facedown in a pile in the middle of the table. KEEP IN MIND There are 6 rectangular faces in a rectangular prism. Opposite sides are the same size and shape. There are 2 triangular facesand 3 rectangular faces ina triangular prism. The triangular faces are the same size and shape. 4 Work in two teams. Each team will select a Prism Card. Then work with your team to find a Surface Area Formula Card showing an expression that could be used to find the surface area of the figure, and a Surface Area Card showing the surface area of the figure. Teams check each other’s work. 5 Continue until all the cards have been matched. Check Understanding ~~ ~~ Does the equation below match the prism? Explain. 2 3 (3 • 4) 4 1 14 • 2 1 15 • 2 5 94 in.2 3 in. 4 in. Go Further ~~ ~~ Choose one of the Prism Cards. Draw and label another prism of the same type with at least one different dimension but the same surface area. ©Curriculum Associates, LLC Copying permitted for classroom use.

FAQs

How do students complete the circle-vocabulary activity?

Students read the problem, use the solution paragraphs, and fill in blanks using words and numbers from the word bank and number bank, using each item only once and not necessarily using all of them.

What does the activity ask students to describe about the sandbox?

It asks students to use circle vocabulary to describe the size of a 5 ft circular sandbox in three different ways.

What is the “Go Further” task about?

Students use as many word-bank words as possible to explain what the radius, diameter, circumference, and area of a pizza reveal about that pizza.
