Write several five-digit numbers in the chart, such as 37,429, and have volunteers read them. Adjusting the Activity Big numbers are broken into groups of digits separated by commas. Each group is read as though it were a separate number. For the larger groups, the name of the group is read. Use a diagram like the one below. Continue to write 5-digit numbers on the lines and have children practice reading them aloud.

Children should get into the habit of thinking and talking about the values of digits in multidigit numbers. Ask questions about the numbers written in the place-value chart. For 37,429 ask: ● Which digit is in the thousands place? 7 ● What is the value of the digit 4? 400 ● How many ten-thousands are there? 3 Repeat using other numbers including those with 0s, such as 5,072. Review the role of zero as a placeholder. Ask: What would happen if the zero were left out of 5,072? The value of the number would not be the same. Encourage children to think in terms of money: $5,072 is not the same as $572.

A number like 4,009 should be read as “four thousand nine,” not “four thousand and nine.” Proper use of and is especially important when reading decimals. See Lesson 5-9. Place Value (Math Journal 1, p. 102) Children use the place values of digits in 3-, 4-, and 5-digit numbers to solve problems.

Directions Children play Baseball Multiplication (Advanced Version). See pages 276 and 277 of the Student Reference Book or Lesson 4-7 for game directions. Members of one team take turns “pitching.” They roll the die twice to get 2 factors. Players on the “batting” team take turns multiplying the 2 factors and giving the product. When a correct product is given, the batter checks the Scoring Chart on the game mat. The rest of the game is the same as a regular game of Baseball Multiplication. 䉴 Math Boxes 5 1 INDEPENDENT ACTIVITY 䉬 (Math Journal 1, p. 103) Mixed Practice Math Boxes in this lesson are paired with Math Boxes in Lesson 5-3.

Which digit is used the greatest number of times on the 100-number grid? 1 is used 21 times. 2. Which digit is used the least number of times on the 100-number grid? 0 is used 12 times. 3. Is the digit 6 used more times in the ones place or in the tens place? It is used 10 times in each place. 4. Use a calculator. Find the sum of two or three rows of the 100-number grid. How much more is the sum of the numbers in a row than the sum of the numbers in the row above it? Why? 100 more. Each number below is 10 more than the number above and there are 10 numbers in each row; 10 10 100. 5. On the back of this sheet, describe the strategies you used to answer Questions 1, 2, and 3. Try to find ways to answer the questions so that you do not need to count each digit. Sample answer: Each digit 1–9 is used ten times in the tens place and ten times in the ones place. 0 is used only in the ones place (except in 100).
