We have been working with numbers and learning different strategies to add and subtract within 20. Recently my first graders learned a new strategy “doubles” to help them add. Doubles are simply adding two of the same numbers together (1+1=2, 2+2=4, 3+3=6…) If students are able to remember their “doubles” addition facts then it should also help them to remember their “doubles plus 1” math facts. For example, if a student knows 8+8=16 then they should also know 8+9=17 (by saying “8+8 and 1 more is…”) Some of my students have gravitated toward using this strategy for difficult math problems but only the children who already have their doubles addition facts down are able to rely on this strategy. So, it is my goal to get my lower students to master their double facts so they too can use this strategy to help them add within 20.
The I-Pads have so many great features. The camera is a simple one that children love using!
Below: I had students make their doubles facts using counters and then take pictures of their work. Students worked together during centers-rolling a 12-sided dice, writing their doubles addition fact on a white board, making it with counters and then taking a picture. Simple, engaging, and they love it!
Here are some of the other doubles activities we are doing in my classroom for extra reinforcement on Doubles and Near Doubles math facts.
