CCSS.Math.Content.1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
We continue to work on fact fluency in first grade. Fact fluency is practiced each day at students’ independent centers. Recently I introduced the “doubles” and “doubles plus one” strategies to my firsties. They are so proud to be able to share all of the doubles they now know!
At the beginning of the week we we worked through understanding the Doubles and Doubles-Plus-1 (or near doubles) strategy with our work mats. Students saw how knowing and understanding doubles helped them to solve many more number sentences quickly. The idea of doubles is that when you have those facts memorized (1+1, 2+2, 3+3, ect.) you then can add problems such as 1+2, 2+3, 3+4 by just adding one to the sum.
After learning about the doubles and near doubles math strategies students were off to practice independently during math centers with their peers. I wanted my students to be able to explore this math strategy with hands on activities that helped them develop this strategy.
|Students sorted doubles and near doubles math facts.|
|Students played Bump with partners to continue practicing doubles and near doubles math facts.|
|Students played “Doubles Dice on Ice!” another math game to promote fact fluency.|
|We used the SmartBoard during centers to match up some “Ladybug Doubles!”|
