Typical strategies include: Memorizing sums to 10, e.g. $7 + 3 = 10$, then using that equation to determine $6 + 3 = \_\_$ or $7+4=\_\_$ Memorizing the doubles, e.g. $7 + 7 = 14$, then using that to determine $8+7=\_\_$ Decomposing/Recomposing. e.g. $9+8=10+7=17$ Using single digit facts to determine sums within 20. e.g. Since $3+6=9$, then we can easily ...
