In math we began doing mental math with two digit numbers. We learned techniques to add two digit numbers in our head. One way is add the tens, then add the ones. Finally, add the two sums together.
26 + 35 = ____.
First add 20 + 30,
then add 6+5.
Then add the two sums 50+11=61.
So, 26 + 35 = 61.
Or, you can add 30 to 26 to get 56,
then add the 5 ones from the 35 to get 61.
Also, we read a story about a brother and sister who set off on a walk around a pond to pick blueberries. Along the way they notice clues of different animals who have been there. We categorized the animals as we read. With your child, talk about the animals mentioned in the story. (The story includes ducks, raccoons, beavers, otters, sunfish, and garter snake). How many of them has he or she seen? Talk about times you have visited a lake, pond, or river. Ask your child what kind of clues did the children see to know the animals had been there?
Fun fact: In the story the children spot the skin of a garter snake. Did you know that lobsters , like snakes, regularly shed their outer covering? After shedding, lobsters often eat their old shell because it contains minerals to help harden their new shell.
