Base 10 Blocks is a Grade 3 mathematics worksheet that helps students represent and interpret two- and three-digit numbers with tens and ones. Across 11 items, students complete fill-in-the-blank questions, draw base 10 models for numbers such as 60 and 118, and identify the number shown by a model. The visual representations reinforce the connection between each digit and its place value. Students also use base 10 blocks to add numbers by counting all the tens first and then all the ones, including a model-based problem such as 57 + 21. This free printable worksheet is useful for guided practice, independent work, or a quick check of students’ understanding of tens, ones, number representation, and concrete addition strategies. It includes a complete answer key for efficient review and grading.

This worksheet helps Grade 3 students represent and identify two- and three-digit numbers using tens and ones, then apply those models to addition. Its 11 items combine drawing base 10 representations, fill-in-the-blank responses, and multiple-choice identification, including addition by counting all the tens before the ones.
Begin by having students build or draw the tens and ones for each addend, such as 57 and 21. Ask them to count the tens first and the ones second, then connect the model to the written sum. Use the drawing items before the multiple-choice addition questions so students explain how the visual model supports their answer.
Watch for students reversing the value of a tens rod and a single cube, or reading a model without separating the tens from the ones. In the addition items, students may count every block without grouping by place value, or combine the digits incorrectly instead of counting all the tens first and then all the ones. Check that drawn models contain the correct number of tens and ones for numbers such as 60 and 118.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also gives schools an option for practicing these number-representation skills with less screen time.
In the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size to make the fill-in-the-blank and number-model prompts easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language. These options can support access to the drawing, identification, and base-10 addition items without changing the targeted skill.
