There is no math homework tonight. Several students have not been turning in reading logs and spelling activities. Please make sure to help your student remember to bring these items tomorrow.

Yesterday we did a science experiment. Try asking your child why ducks can swim and chickens cannot. Ducks have adaptations that help them swim. We observed two of them. (webbed feet, and a waterproof oil for their feathers).

Here is another math example for you. (subtraction, 3rd grade level)

171 - 83

Keep the first number together, and break the 2nd number apart.

171 - 70 = 101

101 - 10 = 91

91 - 3 = 88

I broke the 83 into 70, 10, and 3. There are other ways to break it up though. 71, 10, and 2 would have worked well for this problem as well.

Number lines are also very useful to find the difference between two numbers.
Let me know if this is helpful!
