Using tables to understand decimals

Our lesson today used data tables and connected them to the skill of working with decimals. We also looked at kilometers and meters as part of our measurement systems.

Thinking about decimal multiplication

Our notes below compared how to add and multiply decimals. In class we noticed how these skills are similar and different and wondered why.

Multiplying decimals with the standard algorithm

Today we explored the steps for multiplying decimals using the standard algorithm. We also compared it to the partial products method.

Comparing different ways to multiply decimals

Our notes today show two different methods of multiplying decimals. First we estimated our product and represented the estimate in an area model. Next we solved for our product using the standard algorithm and the partial products methods.

Using the standard algorithm to multiply decimals

Our lesson today looked at how to use the standard algorithm (or shortcut) to multiply decimals. Here are the steps!

Representing decimals multiplication

Today we continued with looking at different ways of representing decimal multiplication in diagrams and concrete models. Below is a copy of our notes and exit ticket.

Multiplying and representing decimals

Today’s lesson explored how to represent and solve multiplication of decimals in different ways.

Multiplying decimals: new unit introduction

Today we started on Unit 8 in which we learn how to represent and solve multiplication of decimals up to the hundredths place. The pictures below show our introductory notes and our objectives.
