About This Worksheet
This worksheet gives first graders additional practice combining groups of tens and ones to find the total number. Students color the tens rods blue and the ones cubes red before counting everything together. Seeing the blocks in different colors makes it easier for children to recognize that tens and ones have different values. As they complete each problem, students begin to understand that every two-digit number is made from groups of ten plus extra ones. This visual practice builds confidence with place value while preparing students for addition and subtraction.
Curriculum and Grade Alignment
This worksheet is intended for Grade 1 students who are developing a solid understanding of place value. Students should already count by ones and recognize groups of ten before beginning. Representing numbers with base-ten blocks helps children connect concrete models to written numerals. This activity supports CCSS.MATH.CONTENT.1.NBT.B.2 by representing two-digit numbers as tens and ones and aligns with TEKS 1.2.A through the use of concrete and pictorial models. It strengthens the number sense needed for future math success.
Student Tasks
Students color every tens rod blue and every ones cube red. They count the groups of ten first, then count the individual ones. After adding the two values together, students write the completed number in the total box beside each problem. They repeat the process until every set of blocks has been completed.
Common Challenges and Misconceptions
Some students may count every cube individually instead of recognizing each rod as ten. Others may forget to include the ones after counting the tens. A few learners may rush and write only the tens value. Encourage children to point to each tens rod while counting by tens before adding the remaining ones.
Implementation Guidance
Teachers can pair this worksheet with physical base-ten blocks so students can build the same numbers before completing the page. It also works well during small-group instruction, math centers, or independent practice. Parents can create simple bundles of ten using craft sticks or straws to reinforce the idea at home. Asking children to explain how they found the total strengthens understanding.
Details and Features
The worksheet provides multiple sets of base-ten blocks along with answer boxes for recording totals. The coloring activity helps students clearly distinguish tens from ones before counting. The printable format is organized, engaging, and appropriate for classroom instruction, tutoring, homework, or homeschool learning.
