Counting by ones and tens is a mathematics worksheet for Kindergarten through Grade 2 learners building early number sense and place-value understanding. Students work through 15 items: 14 multiple-choice questions and one open-ended question. The tasks focus on adding 1 or 10 to numbers, recognizing how counting by ones and tens works together, and connecting a group of ten ones cubes with one block of ten. The worksheet gives students repeated practice with numbers across the ones, tens, and hundreds places, including cases where adding one moves to the next ten and where adding ten changes the tens place. The open-ended manipulatives question adds a concrete representation to the symbolic number sentences.

This worksheet develops the skill of adding 1 or 10 to a given number and recognizing the place-value changes those additions create. It uses 14 multiple-choice number sentences, one multiple-choice question about combining counting by ones and tens, and one open-ended question connecting ten ones cubes with one block of ten.
Begin with physical cubes or drawings to show that one block represents ten ones, then model how adding 1 differs from adding 10 in a number sentence. Have students explain how the ones or tens place changes before completing the multiple-choice items, and use the open-ended cubes question to check whether they understand the concrete model behind the symbols.
Students may treat adding 10 like adding 1, change the wrong digit, or overlook a regrouping change when adding 1 to a number ending in 9. They may also confuse the number of individual ones cubes with the number of blocks, or select an answer based on a digit pattern without checking the full number sentence.
Wayground provides this worksheet as a printable PDF and as a digital quiz, and it includes a complete answer key for the 14 multiple-choice items and the open-ended cubes question. For printable submissions, scan student work with the Wayground for Teachers app to support efficient grading.
