Ten More, Ten Less Chart Puzzles

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through the first item together as a class, then finish the rest independently or with a partner, encouraging them to talk through their thinking: "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 number chart from 1 to 100 worksheets work well as daily practice, homework, or a focused review activity.

Fill plus shaped hundred chart pieces with 1 more, 1 less, 10 more and 10 less. Each piece is cut from a hundred chart. Up is 10 less, down is 10 more, left is 1 less and right is 1 more. The directions on the page read: Read the number in the middle of each piece. Then, fill in the four empty squares. The answer key shows every answer.

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 number chart from 1 to 100. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Students notice columns share the same ones digit, rows increase by one, and skip-counting sequences create diagonal or column patterns across the grid.

Students can add by moving right (ones) or down (tens) and subtract by moving left or up, turning the chart into a visual calculation tool.

Both approaches have value - filling from memory builds fluency, while completing partial charts develops pattern recognition and reasoning.

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.
