About This Worksheet
This worksheet gives first graders more practice counting groups of tens and ones to find the total number. Students color the tens rods blue and the ones cubes red before counting and writing the final answer. Separating the blocks by color helps children clearly see the difference between groups of ten and individual ones. This visual approach makes it easier to understand how two-digit numbers are built and prepares students for more advanced place value concepts later in the year.
Curriculum and Grade Alignment
This worksheet is designed for Grade 1 students who are developing confidence with place value. Students should already know how to count by ones and by tens before beginning. Counting base-ten models strengthens number sense and supports future work with addition, subtraction, regrouping, and mental math. This worksheet aligns with CCSS.MATH.CONTENT.1.NBT.B.2 by representing two-digit numbers with tens and ones and supports TEKS 1.2.A through concrete and pictorial representations of numbers.
Student Tasks
Students color every tens rod blue and every ones cube red. They count the tens first, then count the remaining ones, and combine them to find the total. Students write each completed number in the answer box beside the matching blocks. They repeat this process until every problem has been solved.
Common Challenges and Misconceptions
Some students may forget that each rod counts as ten instead of one. Others may skip counting the ones after finishing the tens. A few learners may write only the tens digit instead of the complete two-digit number. Encourage children to say, “tens first, ones second,” while solving each problem.
Implementation Guidance
Teachers can use this worksheet during guided math lessons, independent review, or place value centers. Parents can recreate similar examples at home using bundles of straws, popsicle sticks, or groups of small objects. Asking children to explain how many tens and ones they counted helps reinforce understanding.
Details and Features
The worksheet contains multiple base-ten block models with large answer boxes for recording totals. Coloring, counting, and writing all work together to strengthen place value understanding. The printable format is ideal for classroom instruction, tutoring, homework, and homeschool practice.
