Activity 2: Adding and Subtracting

This activity may be used independently, in pairs, or as a class activity on a range of digital devices such as an interactive whiteboard, laptop, i-pad, etc.

Purpose

The purpose of this activity is to recognise and order numbers from 1 to 100, and to practice addition and subtraction facts by using the hundreds board as a number line.

Activities

Using the hundreds board, students could be asked to:

  1. Do addition and subtraction.
    Show how to add or subtract the tens first by counting up or down, then the ones by counting left or right.
  2. Look for addition and subtraction patterns.
    Ask the students to find 4+9, 14+9, 24+9, 34+9, 64+9. Describe the pattern.
    15-7, 25-7, 45-7, etc. describe what these answers have in common. Find other patterns.
  3. Play Bingo.
    The teacher calls problems and students select answers until a row or column is filled and student calls 'Bingo'.
    1. A 5x5 square is selected and outlined to produce the bingo board.
