#### Math with Money

By discoverylab | January 27, 2016 | Literacy, MathematicsWednesday we began to explore the world of math with money. Here are a few skills we worked on with coins.

First we used **estimation**. Each student guessed the number of coins that was in the jar. Next we sorted them.

Each student then **counted**, using the skill of one to one correspondence, their change. We looked at the piles and talked about the value of each coin. We estimated the amount of money we had. The numbers ranged from $20 to $20,000! This is a complex skill so we will keep working on it.

Next we counted each pile of money by 2’s, 5’s, 10’s or 25’s.

Once we had tabulated each individual group, we compared which were **greater than and less than. **

After comparing, we used **addition** to find the sum of the entire pile which was 99 coins and $5.43.

We discussed having an in-class flea market and selling small items that we could price between one penny and seventy five cents.

Thursday we worked with our math project in a new way. First we took turns writing town different kinds of stores and what each store sold. Next we sorted the basket of Unifix Cubes. Each student set up a store with a few colors. Every student was given an allowance and then set the price of the cubes in their store.

I gave each student a “shopping list” of colors to buy to make a delicious stew.

Everyone took turns going to the stores and buying supplies. Harlow had a very expensive store where all the items cost $.25, while Louie had the penny store.

On our second round, we practiced using a bigger than necessary coin so that the shop keep would have to make change for us.

Next we brought literacy work into our math project. We wrote our journal entry about what the name of our Flea Market booth will be and what kind of items we plan to sell.

We made some guides to help us remember which piece of money is which. We taped, in order of value, the coins to the page and labeled with the amount each was worth and the name of each coin.
