This package contains:
--- 54 number facts CARDS to 21 in various formats (see PREVIEW)
--- 10 BINGO BOARDS
--- POSTER - Doubles and Near-Doubles facts
You can use this game as RTI, in a Maths Centre for consolidation, or as a whole class with explicit teaching of the near-doubles strategy (as Doubles-plus-one). Simply divide the class into groups of 3 and give each player 3 counters to cover the numbers on their board. You can cater for up to 30 students this way. This is a great way to differentiate as mixed ability groups will provide the support that less skilled members need.
This game was specifically designed to teach the near-doubles strategy after students were getting a hang of the doubles strategy. I have included a Cheat Sheet because the kids love it and it helps them develop the near-doubles strategy, piggy-backed onto the doubles.
Many students rely on finger counting and this slows down mental computation with larger numbers. Teaching the doubles, then the near-doubles almost simultaneously overcomes this.
I have simpler games to teach this strategy (Bug Catcher), but this one extends the older students a bit more and is more competitive. As they learn their facts (or refer to the Cheat Sheet), they know which card/s they are waiting on at the end and this develops mastery.
I use this game for RTI and especially for those students who rely on counting on their fingers ALL the time. You will find they still need reminding to use the Cheat Sheet, but they get better at it the more they play. This isn't a problem because the game is fun.
This game is all about recognising and using this strategy when they encounter these facts in any other math activity.
