Grade Levels
PDF (3 MB|9 pages)


These are Mathematics tasks that can be used with students to support mental strategies for number bonds to 100. This is an important skill for students to develop as it assists with mental computation of two and three digit numbers. It is also helpful in everyday life when students are calculating how much change they will receive from a whole dollar amount. Prior to this lesson, students should have already have an understanding of number bonds to 10.

Three worksheets have been provided, along with samples of how these might be filled in. As this involves mental strategies used by students, there is no one correct answer and there is great value in discussing the possible methods.

Number cards have also been provided so that students can review the bonds while playing concentration or memory.
