Count and combine

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Encourage students to talk through their thinking as they work: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These count and combine worksheets work well as daily practice, homework, or a focused review activity.

These count and combine worksheets for 1st grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter count and combine from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 1st grade. Practicing count and combine at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

"Count and combine" is written for 1st Grade (Ages 6-7), and it covers Common Core 1.OA.C.6. If your little one is a year younger but already steady on number charts & counting, the page still works. You may just need to read the instructions out loud. And if they are older and count and combine never quite stuck, this is a short review rather than busywork.

Yes, both. We made it for 1st Grade number charts & counting, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with count and combine. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

It introduces the concept of joining two quantities before students see the + symbol, making the abstract operation more intuitive.

After combining concrete objects, students record the two groups and total as a number sentence, bridging pictorial and symbolic math.

It can be used to solidify conceptual understanding even for students who have memorized facts, grounding their knowledge in meaning.

First graders should count to 120 starting from any number, read and write numerals to 120, and understand that the two digits of a two-digit number represent tens and ones (CCSS 1.NBT.A.1, 1.NBT.B.2). They should also skip count by 2s, 5s, and 10s.

A hundred chart helps students see number patterns, practice skip counting, and understand place value visually. Students can color patterns (every 5th number, every 10th number), find missing numbers, and see how numbers increase by rows and columns.

Skip counting means counting by a number other than 1 (by 2s: 2, 4, 6, 8 or by 5s: 5, 10, 15, 20). It builds the foundation for multiplication and helps students count money and tell time. Number chart worksheets where students highlight skip counting patterns make this concept visual.
