Day 36 – Multiplying Decimals and Sharing Shopping Items

Lots of pets, lots of siblings, and wide range of other items. They traded iPads with a neighbor and used those items to answer four questions.  These were pretty basic questions that covered more adding and subtracting with decimals–a good review from yesterday.

We continued on with a new lesson: Multiplying Decimals.  We broke this down into 3 steps:

  1. Estimate, to get an idea of the product
  2. Multiply the numbers, while “ignoring” the decimal  (We talked about what it means to “ignore” the decimal.  Obviously the decimal is important, but to find the digits, we will multiply as if they were whole numbers).
  3. Move the decimal back in the same number of times it was moved “out”.

They were able to get some good practice problems in, and I was pleased with their work!
