Happy Monday Bighorns,
Last week the second graders worked on adding ones up to a 3 digit number using both decomposing and composing strategies. However, this week the 2nd graders are subtracting 1’s and 10’s up to a 3 digit number.
Example 1: Adding ones by making the next ten.
56 + 7 = ____ 1. The next ten after 56 is 60.
↙ ↘ 2. To get to 60 you need 4, so the 7 gets decomposed into 4 and 3.
4 3 Then take the 4 and compose it with the 56 to make 60.
60 + 3 = 63 3. The renamed equation is 60 + 3 = 63.
Example 2: Adding tens by making the next hundred.
450 + 90 = ___ 1. The next hundred after 450 is 500.
↙ ↘ 2. To get to 500 you need 50, so the 90 get decomposed into 50 and
50 40 40. Then take the 50 and compose it with the 450 to make 500.
500 + 40 = 540 3. The renamed equation is 500 + 40 = 540.
After solving the equation, students used the open number strategy to check their answers.
Homework
As was mentioned last week homework for the week will be worksheets because the standards being worked on are not on IXL. This will be the case for the next few weeks.
Fun Fact:
January is National “Thank You” month...give thanks to someone you know!
Thank you for supporting your child’s learning and being involved in their education! It is greatly appreciated.
