Math

Here is what we have been working on in math over the last few weeks:

-composing and decomposing two-digit numbers in a variety of ways, using concrete materials (e.g., place 42 counters on ten frames to show 4 tens and 2 ones; (Sample problem: Use base ten blocks to show 60 in different ways.);

 – determine, using concrete materials, the ten that is nearest to a given two-digit number, and justify the answer (e.g., use counters on ten frames to determine that 47 is closer to 50 than to 40)

This is what we will be working on:

-– solve problems involving the addition and subtraction of whole numbers to 18, using a variety of mental strategies (e.g.,“To add 6 + 8, I could double 6 and get 12 and then add 2 more to get 14
