Place Value Models: Tens and Ones #1

Explore two-digit numbers using place value models of rods and cubes with this first-grade number sense worksheet! Each problem features a two-digit number in the form of place value blocks. Students are asked to record the number of tens, the number of ones, and the final two-digit number.

These concrete models are a great way to help students understand that the two digits in a two-digit number are made up of tens and ones. Visuals allow students to see that a rod is simply a bundle of ten ones, which make a 10. In addition, students can recognize that the numbers 11-19 are made up of a ten and a specific amount of ones, as well as how multiples of 10 are created.      

This worksheet is the first in a three-part series. Don't miss Place Value Models: Tens and Ones #2 and Place Value Models: Tens and Ones #3 for more practice!
