Activity 1 Compare 4-Digit Numbers
jOb ective Know the relationship between 4-digit numbers and be able to use signs of inequality.
1. Textbook Instructions Activity 1 Comparing 4-Digit Numbers
Explain how to compare 4-digit numbers by 1 . You can use base-ten blocks to show 2,645 and 3,123.
extending further from comparing 3-digit
numbers. Which of the 2 numbers is greater? Explain why.
1. Have students count the model blocks to 3,123 is greater. When comparing the thousands place, there are more thousands blocks in
compare two 4-digit numbers. Have students 3,123 than in 2,645. Therefore, 3,123 is the larger number.
compare base-thousand blocks before the
base-hundred blocks since they are greater in 2 . Count the blocks and write the numbers in the blanks.
value.
Let’s compare the base-thousand blocks Compare the 2 numbers and write > or < in the .
for 2,645 and 3,123.
The value of the base-thousand blocks in
3,123 is bigger.
Which is greater out of 2,645 and 3,123?
Three thousand one hundred twenty-three.
2. The numbers in the thousands are equal,
but the numbers in the hundreds are different.
So, have students compare the numbers in
the hundreds.
