We begin the year by reviewing sorting and patterning :)
The following is our focus for this term in Math (Sept-Dec)
REASONING AND ANALYZING- thinking fluently & flexibly about numbers to 10
UNDERSTANDING AND SOLVING-using multiple strategies to solve problems
COMMUNICATING AND REPRESENTING- expresses thinking using objects, pictures, words & symbols)
The following is our focus for this term in Math (Sept-Dec)
REASONING AND ANALYZING- thinking fluently & flexibly about numbers to 10
- Recognizing, forming, & sequencing #’s to 10
- Subitize (perceptual) ex. “I see 8”
- Count – 1-1 correspondence
- Conservation (recognize that a quantity remains the same even when it is spread apart or moved)
- Using strategies for counting, adding & subtracting to 10
- Using reasoning to explore and make connections
- Estimating by comparing something familiar
UNDERSTANDING AND SOLVING-using multiple strategies to solve problems
- Using story mats to demonstrate an understanding of problem solving
- Using multiple strategies to engage in problem solving (using a ten-frame, tallies, number bonds, counters)
COMMUNICATING AND REPRESENTING- expresses thinking using objects, pictures, words & symbols)
- Using manipulatives and/or pictures & symbols
- Using my words and math words
- Acting it out
Term 2 & 3
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 to 20 in many 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 2-digit 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 10-ness. 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. |
