## Counting to 100

CCSS.Math.Content.K.CC.A.1 Count to 100 by ones and by tens

Students will be given ten dimes and told that they are each worth ten cents.  The teacher will have to explain that ten dimes equals 100 cents which is one dollar.  The students will be told that this is how money works in real life; therefore, they will need to know this in the future.  The students should lay out the coins and count by tens until they reach 100! This could easily be changed to work with fives as well!  .

## Finding the Sum of 10

K.OA.A.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.

First, pass out five flash cards to every student in the class.  Have them write the five ways to get the sum of ten with the numbers 1-9 on one side. On the flip side of the card, have them write the answer to the problem.  When completed, put them in partner groups.  Have them ask each other the questions and show the answers once correct.  Until they get the correct answer, have the partner holding the flashcard help with problem solving methods. In doing so, this creates a visual tool (flash cards) and a different perspective with problem solving (the partner) in learning how to get the sum of ten with the numbers 1-9.
