Sample Additional Practice Exercise 1

Count the cubes. Write the numbers to tell how many. Then draw a circle around the number that is greater than the other number. Mark an X on the number that is less than the other number.

A group of 2 color cubes and a group of 4 color cubes. The number 2 is written next to a cube. The number 4 is written next to another cube. The number 2 is marked with an X. The number 4 is circled.

Count one color cubes. There are 2 of one color, so write 2. Count the other color cubes. There are 4, so write 4. When you count, 2 comes before 4. So, 2 is less than 4, and 4 is greater than 2. Mark an X on 2 and circle the 4.
