K.CC.7: Comparing Numbers

1. Counting Objects

Use two groups of objects (like blocks or buttons) to represent the numbers being compared. Count each group and compare which has more or less.

2. Number Line

Use a number line to show that numbers further to the right are greater. Mark the two numbers being compared and see which is further to the right.

3. Ten Frames

Use two ten frames to represent the numbers being compared. Fill in the frames with counters and visually compare which has more.

4. Greater Than/Less Than Symbols

Introduce the alligator mouth analogy: the alligator always eats the bigger number, so the mouth (> or <) opens toward the larger number.

1. Snack Time Math

Give your child two small piles of snacks (like crackers or grapes). Ask which pile has more, which has less, or if they're equal. Let them count to check.

2. Comparing Collections

Create two collections of household items (buttons, toys, etc.). Have your child count each collection and compare which has more or less.

3. Domino Compare

Use dominoes to compare the number of dots on each side. Ask which side has more dots, which has fewer, or if they're equal.

4. Number Books

Read books that involve comparing quantities. Ask questions about which page has more or fewer objects.

5. Greater Than/Less Than Monster

Create a "number muncher" monster from a paper cup or sock. The monster's mouth (opening) always eats the bigger number. Use it to practice comparing numbers.

1. Use Concrete Objects

If your child struggles with abstract number comparisons, use physical objects they can count and compare.

2. One-to-One Correspondence

Line up objects from each group in one-to-one correspondence to see which group has extras or which runs out first.

3. Focus on Vocabulary

Practice using the terms "greater than," "less than," and "equal to" consistently. You can also use "more than," "fewer than," and "the same as" for younger children.

4. Start Small

Begin with numbers that are far apart (like 2 and 9) before moving to numbers that are closer together (like 7 and 8).

5. Use Visual Aids

Create comparison cards with the symbols >, <, and = to help your child remember which symbol to use.

Activity 1: Number War

Use playing cards (ace through 10). Each player flips a card, and the player with the higher number takes both cards. The player with more cards at the end wins.

Activity 2: Roll and Compare

Roll two dice and compare the numbers. Have your child tell which is greater or less, or if they're equal.

Activity 3: Number Hunt

Look for numbers in your home or neighborhood. When you find two numbers, compare them using "greater than," "less than," or "equal to."

Activity 4: Fill in the Symbol

Write number pairs with a blank space between them (e.g., 3 ___ 7). Have your child fill in the correct symbol (>, <, or =).

By the middle of the year, your child should:

• Compare groups of objects to determine which has more or less
• Begin to compare written numbers with support
• Understand the vocabulary of comparison (more, less, same, equal)

By the end of the year, your child should:

• Compare two written numbers between 1 and 10
• Use the terms "greater than," "less than," and "equal to" correctly
• Begin to use the symbols >, <, and = (though this may extend into 1st grade)
• Explain their reasoning when comparing numbers

Simple Assessment:

Write pairs of numbers between 1 and 10 on paper. Ask your child to tell which is greater or less, or if they're equal.
Create two groups of objects (5-10 items each). Ask your child to count each group and tell which has more or less.
If your child is ready, have them place the correct symbol (>, <, or =) between pairs of numbers.
