What Is the “10 More Or 10 Less” Worksheet?
The 10 More Or 10 Less worksheet is a printable activity designed to help primary‑age learners practice adding and subtracting ten. It aligns with Unit 5 of many elementary math curricula, where the 10 more / 10 less game introduces the concept of place value and reinforces mental math strategies.
Why Use a 10 More Or 10 Less Worksheet?
Working with tens builds a solid foundation for later operations such as multiplication, division, and estimation. The worksheet offers several educational benefits:
- Reinforces place‑value understanding by encouraging students to look at the tens column first.
- Develops mental addition and subtraction skills, which improve speed and confidence in everyday calculations.
- Provides a low‑tech, hands‑on activity that can be used at home, in the classroom, or during remote learning.
- Supports differentiated instruction; teachers can adjust the difficulty by adding word problems or using a hundred chart.
How the Worksheet Fits Into the Unit 5 “10 More / 10 Less” Game
In many school programs, Unit 5 introduces the 10 more / 10 less game as a playful way to explore number relationships. The worksheet extends that game by giving students a structured format to record answers, check their work, and reflect on strategies.
Typical Worksheet Layout
- Number prompts – e.g., “45 + 10 = ?” or “73 – 10 = ?”.
- Space for students to write the answer.
- A column for “How did I solve it?” where learners note whether they used a number line, a hundred chart, or mental math.
Integrating Video Instruction
Many teachers pair the worksheet with a short instructional video. The video—recorded with Screencast‑O‑Matic—continues the series on place value and demonstrates how to add ten using a hundred chart. After watching, students complete a Seesaw activity that mirrors the worksheet tasks.
- Step 1: Play the video in class or assign it for homework.
- Step 2: Pause at each example and ask students to predict the answer before it is shown.
- Step 3: Direct learners to the Seesaw activity where they upload a photo of their completed worksheet.
Using a Hundred Chart to Find “10 More” or “10 Less”
A hundred chart is a visual grid of numbers from 0 to 100. It is especially helpful for the 10 more or 10 less concept because each row represents a complete set of ten. To use the chart:
- Locate the given number on the chart.
- Move one row down to add ten, or one row up to subtract ten.
