This package contains:
---44 NUMBER FACT CARDS (and 1 CHANCE CARD)
---10 BINGO BOARDS
You need to supply 9 counters (or buttons or similar) to cover the numbers as they are called as answers to the number facts.
You can use this game with small groups as an Intervention strategy or you can add it to a Maths Centre. You could also group your students and use it across the whole class. With 10 boards you can cater for 30 students in groups of 3. Each player in the group takes turns and has 3 counters. This is a supportive strategy with all players in the group providing the answer (good for mixed ability groups).
I use this game with small groups of students who are at this stage needing to memorise subtraction number facts from 20. The number line is necessary to begin with, but you can black it out once students are becoming proficient.
I have added a chance card and players can use this to call their own number fact to match a number on their board. This adds a random fun element which kids enjoy.
