This week we’ve been working on some tough problem solving in our Measurement unit. It’s been awesome to see how the students attack problems with more confidence, share their ideas with one another (communicating using mathematics language) and use estimation to decide if their solution is reasonable. We’ve seen a lot of growth since September, and I just wanted to share the problem we attacked together. Ask your child to explain how their group attacked the problem!

First, we watched this video.

We decided as a group that we wanted to solve the following problem: How many sticky note will it take to cover the bulletin board?

Students then identified what kind of information they might need to solve the problem. They threw out ideas such as:

• how many sticky notes it takes to cover one row of the bulletin board
• how many stick notes fit down the side of the bulletin board
• length and width of bulletin board
• length and width of the sticky note

Students were given the dimensions of the bulletin board, and dimensions of the post it notes.

This was the final solution:

We also talked about sources of error and why our solutions might be a little off. We have a test on Thursday! Reviews were sent home last week.

It will cover the following concepts:

• elapsed time
• linear measurement and conversions (converting mm to cm, cm to m, m to km, and vice versa)
• perimeter and area of rectangles (using a formula for the area of rectangles A= lxw and formula for perimeter P= (l+w) x2)

Students are also encouraged to play Prodigy as I have assigned a variety of review questions to help them practice their skills.

#### We have been learning about the 24-hour clock and elapsed time! Challenge your child at home to tell you what time it would be using the 24-hour clock. Or ask them questions about how much time has passed.

Here is a video I created to demonstrate 5 different strategies you can use for division.

Today, we were playing with Cuisinaire Rods to determine different relationships between “the whole” and fractional pieces. Students made their own videos to explain their thinking using the Explain Everything App. Check out their work here!

Today we tried out our very first Number Talk. A Number Talk is an activity that helps build mental math strategies, confidence and communication about math ideas. Check out all the strategies we got for this simple computation. If you want to build confidence in math, try this at home!

Over the course of this week, we’ve been learning all about how our brains learn math. We’ve learned that mistakes help us learn; our brain actually makes more connections when we make mistakes! We’ve also talked about perseverance and working together in a team.

Today we completed an “impossible” paper sculpture activity. Can you build this sculpture? Many of us could! It just took some thinking, some sharing of ideas and A LOT of mistakes!
