We want students to be very comfortable identifying the parts (tens and ones) in a two-digit number. It's very helpful to actually make these larger numbers. This knowledge will build our number sense and eventually be used in addition problems.
Place Value Mat:
Use this building mat and paper base ten blocks to make larger numbers. We focus mainly on tens and ones. However, feel free to expand into hundreds if your child is ready.

Tens & Ones Counting Activity:
This is an example paper that you could easily adapt to what you have at home. Have your child count a large number of objects by making groups of ten. Then, he/she can figure out how many tens and ones there are and use that to discover the total number of objects.

Tens & Ones:
Choose some two-digit numbers to write in expanded form (tens and ones). You could cut up a 100s chart to get some ready made numbers. Write an equation showing tens and ones. For example, 4 tens + 8 ones = 48.

Write, Make & Expand:
Choose some two-digit numbers to make and expand. You could cut up a 100s chart to get some ready made numbers. Write the number in the first column. Make or draw what the number would look like with base-ten blocks. Draw sticks or lines to show a tower/rod which is a group of ten ("tens"). Draw a small box to show "ones". Finally, expand the number into an equation showing tens and ones. If you're a little confused, don't worry! The first row on the page is done for you as an example.

Base Ten Bingo:
Play this great game! Students will count base ten blocks (tens and ones) to mark Bingo numbers and try to fill in a row or column. Have your child play with tens and ones first. When that is mastered, extend to hundreds.
