Use Math Masters, page 119 to assess children’s ability to write whole numbers
up to five digits. Children are making adequate progress if they successfully
complete Problems 1–3. Some children may be able to complete Problems
4 and 5.

Use a transparency of Math Masters, page 422 or semipermanent
chalk to draw a place-value chart to ten-thousands on the board.
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.
Include numbers with several 0s.

NOTE Children may have trouble with
algorithms because they do not understand
what the digits in a number represent.
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.

Watch for children who insert the word and after thousand when reading a whole
number. 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.

Frames and Arrows
Have your child read and solve the three Frames-and-Arrows problems. Review the rule that
is being used in each puzzle. Ask your child to look for patterns in the frames. For example,
which digit changes when adding or subtracting 10? (tens digit and hundreds digit change
when moving from the 8,800s to the 8,900s) 100? (hundreds digit and thousands digit change
when moving from the 8,000s to the 9,000s) 1,000? (thousands digit and ten-thousands digit
change when moving from the 9,000s to the 10,000s)

strategies they used to find the digit counts without necessarily
having to count each.

1. 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).
