This printable worksheet is a great learning activity for grade 1 children that helps them to break two digit numbers into the corresponding numbers of "tens" and "ones". Practicing with this resource helps the child to understand our base of 10 number system. A clear layout will help organize the process of analyzing and calculating numbers.

This math activity is essential for children to build up good understanding and confidence identifying tens and ones in a variety of numbers up to 99.

You can start this worksheet by asking a child to write numbers into the boxes at his or her own speed. To add challenge to the task you can set a time limit which would still be accessible for a child – 5 to 7 minutes. Depending on the learning style and the pace of a child add more variety by cutting or folding this worksheet (use the vertical line as a guide) and leave the second part for a later time or for homework.

In order to use it as a game take one or two dices and roll it/them. Take turns with a child. If there is a number five – look for all 5 tens or 5 ones on the task. A child finds 58 and writes 5 in the tens box. Roll again and look for the next number that you have. Game is over when you complete the whole worksheet.

You can also look for a random number generator online and set the range of numbers from 1 to 9. A number appears on the screen. A child looks for a number and fills in boxes of tens or ones.

This activity is suitable for 6 to 7 years old students, U.S. school 1st grade.
