Composing and decomposing teen numbers the fun way!

The past two weeks, we have continued working on composing and decomposing numbers. Earlier in the year, we worked on making numbers to 10. Now, we are adding how to make numbers from 10-20.

To do this, we have used double ten frames to show that a "teen" number is just a combination of 10 and some ones.

To give the students practice in composing these numbers, we played a little game.

                                                  

The students were given partners using the random chooser application on our smart board. This is a great way to mix up partners and have children work together who may not ever choose to work together.

Then I used the program to randomly choose a number between 10  and 20.

One partner made the number using unifix cubes on their double

ten frame while their partner wrote the number sentence to represent their number on their dry erase board.

The students took turns making the number using the double ten frames and writing the number sentence to show the number.

Was this a fun way to learn math?! Yes!!
