Math Facts
Research shows that students do not benefit by learning math facts through rote memorization, but rather application of specific fact strategies. Below are the strategies, plus flashcards and games that can be printed and played at home to practice. I recommend putting games in a clear plastic page protector and writing on it with a dry erase marker, so that it can be reused. For homemade spinners, use a paper clip and pencil. If you need items to cover numbers, like on Bump, I have attached Red/Yellow Counters below that can be printed and cut out.
Cada día vamos a pasar 5 minutos practicando estrategias. En las pruebas de viernes, tienen 1 minuto 30 segundos para pasar. Necesitan lograr 18 problemas correctos o más para pasar a la próxima estrategia. Si no pasen, quedan en la misma estrategia por otra semana. Recuerden...esto no es de solo contar y memorizar...es para aplicar las estrategias y por esa manera mejorar su fluidez de facts.

Doubles (e.g. 3+3=6....goes up to 10+10=20)

Halves (The opposite of doubles. If you know the double fact 4+4=8, then you know the Halves fact of 8-4=4.)

Making Ten (All the ways to make ten. 0+10, 1+9, 2+8, 3+7, 4+6, 5+5 and their turn around facts: 0+10, 9+1, 8+2, 7+3, 6+4)
|

Subtract From 10 (Opposite of Making 10. 10-9=1, 10-8=2, etc. If you know 4+6=10, then you know 10-6=4.)
|
|
|
Near Doubles (Also called Doubles +1 or -1, this means you can use your knowledge of doubles to help you do facts that are almost doubles. For example, if you know 3+3=6, when you see 3+4, think of it like 3+3+1. Then you add the double 3+3 and then 1 more to equal 7. Another example, if you know 7+7=14, then you know 7+6 is the same as 7+7-1=13.)
|
|
|
|
|
+10 (Adding ten more to a number. Total sum will be 20. So like 3+10=13. Or 10+7=17.)
|
|
|
|
|
-10 (The opposite...taking 10 away from a number. For example, 11-10=1 or 15-10=5.)

Ten Is a Friend (Using your knowledge of making ten to help you do harder facts. I recommend using the double ten frames and red/yellow counters below to help solve these in the beginning. It will initially be practiced at school this way, too. Examples: 7+5....you know 7+3 makes 10 and there is 2 left over, so that´s the same as 10+2...so the answer is 12. Put 7 red counters on top ten frame and 5 yellow counters on bottom ten frame. Move yellow counters to fill top and make 10. This shows you have 2 left making 12. Another example: 8+6. You know 8+2 makes 10 and 4 left over, so 10+4 and the answer is 14.)
