Addition and Subtraction to 20 Game for Years 1 and 2: Sugar Sprint
This addition and subtraction to 20 game for Year 1 and Year 2 is Sugar Sprint, an interactive whiteboard racing game by Teach This aligned to the Australian Curriculum. Students add and subtract within 20 and recall addition facts to 20 with their related subtraction facts. Four teams each pick a candy racer and answer 15 multiple choice questions, such as 8 + 5 and 9 + 9. Teams write A, B, C or D on a mini whiteboard, then tap their answer on the board. A correct answer unlocks the team's Go button and moves its racer one step, and the first racer to finish after 11 steps wins.
It opens in Microsoft PowerPoint on any interactive whiteboard, panel or projector, with no macros, no student logins and no student data collected. A race takes 15 to 20 minutes, and the notes give a make-ten or doubles strategy for every question, so a relief teacher can model the thinking as the class plays.
Learning goals
- We are learning to add and subtract numbers within 20, using a variety of strategies, e.g. counting on, counting back, partitioning, subitising and part-part whole knowledge of numbers to 10 and to use the language of 'plus' and 'minus' in story problems.
- We are learning to recall addition facts to 20 and apply to related subtraction facts using a range of strategies.
- We are learning to use a range of strategies, to solve simple addition and subtraction problems.
- We are learning to use a range of mental and written strategies to solve simple addition and subtraction problems.
- We are learning to explore number sequences by twos, threes, fives and tens from any starting point.
- We are learning to use a range of mental strategies to solve simple addition and subtraction problems.

Differentiation
Modifications
Give teams counters, a ten frame or a number line to work out each question. Seat a confident student in each team to model counting on from the bigger number.
Extensions
Ask each team to explain the strategy they used before the answer is shown. Challenge students to write the matching addition fact for each subtraction question, such as 6 + 8 = 14 for 14 take away 6.
