FAQs
What does the Number Bonds 100 worksheet help students learn?
This Grade 1–2 worksheet helps students find the missing difference in nine fill-in-the-blank equations such as 100 − 50 and 100 − 20. Completing the set builds fluency with subtracting multiples of 10 from 100 and reinforces how tens relate to the whole of 100.
How can I use this worksheet to teach subtracting multiples of 10 from 100?
Begin by modeling one equation with base-ten blocks, a hundreds chart, or tens language, such as explaining that 100 is 10 tens and subtracting 2 tens leaves 8 tens. Then have students solve the remaining fill-in-the-blank equations, asking them to explain how the number of tens subtracted helps them find each difference.
What mistakes should I watch for on the Number Bonds 100 worksheet?
Students may write the number being subtracted instead of the difference, such as entering 20 for 100 − 20, or lose track of the tens when subtracting a multiple of 10. Check that they understand the blank represents the amount left after subtraction and encourage them to use tens or a hundred chart to verify each answer.
