These worksheets are designed to help young learners practise subtraction using a hundreds chart. The activity is ideal for building foundational number sense, enhancing subtraction skills, and developing confidence with subtracting 2-digit numbers.

How to Complete:

To solve each problem, students will locate the first number in the subtraction equation on the hundreds chart. Have them partition the second number into its tens and ones. They will move up to subtract tens and to the left to subtract the ones. After finding the final number on the chart, students write their answer in the space provided.

Additional Tips:

1. Demonstrate how to use the number chart to solve a subtraction problem before starting the activity.
2. Enlarge the worksheets to A3 and place them into write and wipe sleeves. Provide counters or markers for students to track their movements on the chart as they solve each problem.

Extension Ideas:

1. Create Your Own: Allow students to create their own set of subtraction problems to solve with the hundreds chart.
2. Reverse Activity: Provide the answer (difference) and the smaller number (subtrahend), then ask students to determine the missing number (minuend) using the chart.
3. Pattern Exploration: Discuss patterns in the number chart, such as the consistent subtraction of 10 as they move up a column.
