Identify a larger amount, smaller amount, and difference. Comparison problems are challenging because nothing is being added or taken away, so it is not obvious how to proceed. Use bar models to label and draw the relationship between the amounts. Use these visual models to make sense of key words in an intuitive way.
Compare 2 numbers. The larger number is how much greater than the smaller number? The smaller number is how much less than the larger number? Find the difference by adding to the smaller number to make the larger number, or by subtracting the smaller number from the larger number. Prerequisites: K-108
Compare 2 numbers using the word "more" in an intuitive way. Given the smaller number and how many more is the larger number, find the larger number. Add the difference to the smaller number using a Make 10 addition strategy and ten frames, number bonds, or mental math. Prerequisites: 1-73 ○ 1-45
Compare 2 numbers using the words "less" and "fewer" in an intuitive way. Given the larger number and how much less or how many fewer is the smaller number, find the smaller number. Subtract the difference from the larger number using the Make 10, From 10, or Missing Part strategy. Prerequisites: 1-74 ○ 1-60
