You may use the Discard box once. Once you write a digit in place, you may not move it. After you have fi lled all fi ve boxes, compare your numbers with your friends.Goal: Make the greatest number in your group. LESSON 11: APPLY Directions: Refl ect on your learning. Think about a strategy you used to create the greatest number in the Place Value Game. Explain your strategy in the box below.LESSON 11: MATH JOURNAL LESSON 12: APPLY Directions: Follow the directions in each step below. Draw a model of the number in the place value mat below. LESSON 13: APPLY Directions: Flip over a card and write the digit in a place value box. You may use the Discard box once. Once you write a digit in place, you may not move it. After you have fi lled all six boxes, compare your numbers with your friends. Directions: Refl ect on your learning. What strategies do you use to compare really big numbers? Write about them below. LESSON 14: APPLY Directions: Write each number in expanded form. Then practice reading each number in standard and expanded form (whisper). Directions: Circle all the GROUPS of items you see below in the grocery store picture. Directions: With a partner, determine the total number of items in each group. Record the name of the group and then show how you found the total. See example. LESSON 16: APPLY Directions: Look at each star array and record the number of ROWS and the number of stars in each ROW. Then fi nd the total number of stars. Use the work space on the next page to show how you found the total. Directions: Look at each star array and record the number of COLUMNS and the number of stars in each COLUMN. Then fi nd the total number of stars. Use the work space on the next page to show how you found the total. Choose an array from the Apply activity. If each star costs 2 LE, how much would it cost to buy the whole array? Draw the array that you chose below and then determine the cost. Do as many as time allows. Directions: Look at the star array below. Some of the stars have been ripped off . How many stars were in the original array? Explain your thinking using pictures, numbers, or words in the box below the star array. LESSON 17: MATH JOURNAL Directions: Refl ect on your learning. Look at the two images below. Then, in the box answer the following questions.• How are these similar?• How are these diff erent?• Find the total. Do they both have the same total? How is that possible? LESSON 18: APPLY Directions: In each box, play a round of Circles and Dots. Roll the die one time to identify the number of circles you will draw. Roll it again to identify how many dots you will draw in each circle. Once you have drawn your models, record a repeated addition equation and a multiplication equation. Then compare your product with your partner’s using . See the example below. Draw a Circles and Dots board for the following equations and then fi nd the product: LESSON 19: APPLY, Part 1 Directions: Solve the problems below to determine whether or not there is a Commutative Property of Multiplication. Directions: On the grids below, draw arrays that prove the Commutative Property of Multiplication. Label your grids with the factors (the two numbers you are multiplying) and products (the answers). Directions: Refl ect on your learning. In the box below, explain multiplication and the Commutative Property of Multiplication. You can use words, pictures, or numbers Directions for Array Block Game:• Roll the die one time. That is the number of rows in your array.• Roll the die a second time. That is number of columns in your array.• Decide where you would like to create the array in the game board grid. • Draw the array on your grid and color it in. • Label the array with a multiplication equation and the product. Play until you cannot fi t any more arrays on the grid. LESSON 20: APPLY
