Teaching Math Skills with Technology:
Common Core Standards K.OA.2 Add and Subtract within 10

Today's math lesson was a review of ways to add to ten. First, we practiced on our fingers- a tool that is always with us!

Then, we used a great free app- Find Sums by Math Tappers Their description from the iTunes store"MathTappers: Find Sums is a simple game designed to help learners to make sense of addition (and subtraction as a related operation), and then to support them in developing accuracy and improving their speed."

The students used a ten frame and selected numbers that added up to ten. The game tracks accuracy and speed, so the children kept playing to try to get 100% accuracy and fast. I was amazed at how many kids were chanting '8 and 2' '7 and 3' '5 and 5' as they played. They math addends until are are done.  They can also add up to 20, and 100 using the apples.

Right after, We used a deck of cards with A-J and the 10's Go Fish with the cheat sheet printable from by Shari Sloane "10s Go Fish - This game is played just like "Go Fish." Instead of asking for a card to match your card, you have to ask for a card that would add with one of your cards to make a sum of 10." Thanks Shari for your awesome math games! My students love them.

Using fingers, apples and ten frames, and playing cards my kindergartners "got" how to add to ten!
