Compare Whole Numbers to 100

Comparing numbers that are just before, just after, between, greater than, and less than are important skills for the children to become proficient in.

Materials: number cards 0 – 10 Preparation: Place the number cards on a table.

Prerequisite Skills and Concepts: Children should be able to count and write numbers 0 – 10 and should be familiar with ordering numbers 0 – 10.

  • Say: Today we are going to learn about numbers that come just before, just after, and between. We are also going to work with numbers that are greater than and less than other numbers. We will begin by looking at numbers that are greater than and less than other numbers.

  • Ask: Would someone come up and choose a number and put it in the chalk tray? Now would someone else like to choose a number and place it next to the other number?

  • Say: Let's all look at that number. (Point to the second number chosen.)

  • Ask: How many of you think that this number is greater than the first number? How many think that it is less than the first number? How do you know?
    Elicit from children the correct answer and whether it comes before, and is less than the first number, or comes after, and is more than the first number.

  • Continue this activity until children have an understanding of greater than and less than.

  • Say: Now we are going to talk about numbers that come just before, just after, and between.

  • Place a number such as 6 in the chalk tray.

  • Ask: Who can come up and pick out the number that comes just before 6 and place it in the chalk tray just before 6?
    The child should pick 5.

  • Ask: How do you know that is the correct number?
    Elicit from the child that when they order or count numbers 0 – 10, the 5 comes just before 6.

  • Remove the numbers and place two numbers such as 5 and 7 in the chalk tray with a space between.

  • Say: Look at the two numbers that are in the chalk tray.

  • Ask: Who can find the number that comes between these 2 numbers?
    The child should choose 6.

  • Ask: How did you know to pick 6?
    The child should say that when he/she counts or orders numbers, 6 comes between 5 and 7.

  • Continue having children work with numbers that come just before, just after, and between, and numbers that are greater than or less than.
