Double the trouble, double the fun. Join us in this mighty video as we learn our doubles facts. Doubles are just an easy way to memorize addition and subtraction facts, such as 5+5 or 7+7. Once we memorize doubles, we can move to doubles plus 1... WHAAATT?? Just trust me, we're one doubles step ahead of everyone else.
Memorize and practice doubles addition facts, such as 2+2=4, 3+3=6 and so on
Understand that doubles facts help solve addition and subtraction problems
Learn to use doubles facts to solve similar addition and subtraction problems
Learn the "doubles plus one" strategy for memorizing addition facts
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
