# Final Assignment – Estimation Challenge

For our final activity I started the off with this……

we filled in too high, too low, and best guesses! Then we checked the answer…..

Completing this challenge got the students pumped and hooked into doing some math on our very last days of class (especially with some students exempted from the final exam). Our final assignment is to …

We got out the iPads and I let the kids work….. here is what a few came up with:

A lot of kids did water filling or post it note covering estimates. Some kids ended up making an all-out 3 Act math problem.

### How many caps will fill the marker?

—————————————————————————–

### How many cups to fill the shape?

—————————————————————————–

### How many post-its will cover this triangular wall:

Act 1: She put a photo and a small video in Explain Everything to start us off.

and

Act 3: Made a time lapse video and provided a screen shot with the answer

Grab her Explain Everything File here

—————————————————————————–

### How many stickies to fill the door window?

And hit us up with a time lapse video for the answer:

—————————————————————————–

### How many water bottles will fill the hexagonal prism?

Watch the water fill up by grabbing her Explain Everything File

A fun last few days….and I’ve got some new estimates for class next year.

# Trashketball – A Spiralled Lesson!

This was our multi-day, curriculum-spiralled, activity this week!

### Day 1 – Filling the Bin!!

Let’s get curious!!…..I showed this video from Andrew Stadel, and took questions & wonderings:

We settled, (I chose) on the question on how many paper balls would fill a bin! They made predictions, too high, too low and right on!

They made paper balls and found their diameter. We agreed that each ball could be different so we recorded everyone’s diameter and averaged them to give the “average ball size”

# Distance-Time Graphs – Gallery Walk

The last few semesters I ran this two-day lesson on distance-time graphs. Today I added a new twist on Day 2.

Recap: Day 1 – A few prediction videos on water height in a cup vs. time. Then WATERLINE by Desmos!

Day 2:  Today

Warm Up – We reviewed the previous day’s work by choosing one of the cups from the picture and drawing a water-height vs. time graph.

Not surprisingly, no students chose to draw the graph for the Stanley Cup. After they make their sketches we dove into using the CBR Rangers from Vernier just like on Day 2 from the previous post. They walked in front of the Ranger taking various different walks and we all saw their distance-time graphs in real-time. For each walk the students made prediction graphs on their whiteboards before seeing the live graph.

I wanted more predictions from them so I showed them a video I made. They were to watch the video and make a prediction graph of my distance away from the camera vs. time.

After take up of this graph they were to create their own video on the iPads. Each pair of students we’re given a scenario to film that described motion.

Here are two motion videos they filmed: Very basic to start!

They had to create their distance-time graph and hide it under the flap on the vertical whiteboards.

Pairs then went on a gallery walk. They watched each student made video, graphed the matching distance-time graph and then checked the answer under the flap.

Kids enjoyed it and they practiced lots of different distance-time graphs.

# Is Lego Gender Biased?

Here was how our conversation in math class (MFM1P) went…..How many pieces make up this Star wars Lego ship? We started with that picture and had a great conversation around Lego.

Then I showed this one.

Does the pool/hot tub have more pieces/less pieces/ or the same? This turned into “boy” Lego vs. “girl” Lego. My personal opinion is its all great…. My 3 daughters are just as excited to play with Yoda as they are with Disney princesses. Girls in the class agreed that they didn’t need their own line of lego!!!

I moved our conversation a little forward with asking Which costs more? And which should cost more?
