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

How to Complete:

To solve each problem, students will locate the first number in the addition equation on the hundreds chart. Have them partition the second number into its tens and ones. They will move downward to add tens and to the right to add 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 an addition problem before starting the activity.
2. Provide counters or markers for students to track their movements on the chart as they solve each problem.

Extension Ideas:

1. Challenge Problems: Create additional equations that result in answers over 100 to encourage students to visualise numbers beyond the chart.
2. Reverse Activity: Provide the answer and one addend, then ask students to determine the missing number using the chart.
3. Pattern Exploration: Discuss patterns in the number chart, such as the consistent addition of 10 as they move down a column.
