Adding with pictures (sums to 20)

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 adding with pictures (sums to 20) worksheets work well as daily practice, homework, or a focused review activity.

These adding with pictures (sums to 20) 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 adding with pictures (sums to 20) from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 1st grade. Practicing adding with pictures (sums to 20) at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

"Adding with pictures (sums to 20)" 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 addition, the page still works. You may just need to read the instructions out loud. And if they are older and adding with pictures (sums to 20) never quite stuck, this is a short review rather than busywork.

Yes, both. We made it for 1st Grade addition, 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 adding with pictures (sums to 20). In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Sums exceeding 10 require students to recognize teen numbers and write two-digit answers, adding place value awareness to the addition task.

Coloring exactly 10 objects one color and the rest another helps students see how to decompose one addend to make a ten, visualizing the strategy.

Once students consistently count on rather than counting all objects, they are ready to solve addition problems written as number sentences without picture support.

By the end of first grade, students should fluently add within 10 (CCSS 1.OA.C.6) and solve addition problems within 20 using strategies like counting on, making ten, and decomposing numbers. They should also add within 100 using place value understanding (1.NBT.C.4).

Start with adding a two-digit number and a one-digit number, then progress to two two-digit numbers. Use place value understanding: add the tens first, then the ones. Base-ten blocks and place value worksheets make this concrete before moving to abstract equations.

Key strategies include counting on from the larger number, making a ten (e.g., 8+5 becomes 8+2+3), using doubles (6+6=12) and near-doubles (6+7=6+6+1), and decomposing to known facts. Worksheets that practice each strategy separately help students build fluency.
