Math Topic 4

In Math we will be learning to multiply whole numbers and decimals to hundredths. We began the unit learning how patterns to place the decimal point when a decimal is multiplied by a power of 10. We will also estimate decimal products. We will look for structure and patterns to help us to predict answers and understand concepts. 

This topic uses money as a real world context to connect what we are doing in room 22 to everyday life. 

Here is something you can do at home to practice:

1. Look at grocery sale ads.

2. Choose one item and decide the number of items that you want to buy. (2 or more)

3. Estimate about how much the purchase will cost. Students can round to whole numbers or compatible numbers (numbers they deem easier to work with). 

For example: 

Choose to buy 4 of an item that costs $2.89. 

4 x $2.89 is close to 4 x 3 which is $12. 

Choose to buy 16 of an item that costs $3.18.

16 x $3.18 is similar to 15 x 3 so the total cost will be about $45.

Happy shopping!
