Numbers to 20
Things to practice:
counting on, counting back
sequencing numbers to 20
skip counting by 2's and 5's to 20 (and beyond)
finding patterns in skip counting
greater than/less than
representing numbers in different ways (tallies, pictures, ten frames etc.)

THE BIG MATH IDEAS ARE: *A ten frame helps us to organize numbers in 5 and some more. A full ten frame holds 10. When we see a ten frame, we can see how many more we need to get to 10. Mathematicians use ten frames to build and represent 2digit numbers. *When we count a set, we can count in many ways by 1's, 2's, 5's or 10's and some more. The answer is always the same! *Mathematicians make sense of bigger numbers through place value. There are patterns in place value based on 10ness. the teen numbers all have ten and some more. After that, we can count in 10's and some more. *We can compare and order big numbers like we do small ones. *We can add or subtract bigger numbers like we do smaller ones. *It's a good idea to estimate the sum and difference before we add or subtract. *When we add bigger numbers, we use the idea of partitioning. We add tens, then ones. Same for subtraction. *Using ten frames can help us make sense of addition and subtraction of bigger numbers. Measurement Big Ideas:
