## How tall are we?

Today we used the “cup” as a unit of height. Each group had only 4 cups and had to determine how many cups tall one group member was.

There were no restrictions given on how to arrange the cups or how to solve the problem.

Some groups wanted to use string, some wanted meter sticks, some wanted rulers…

Some groups used dividing, and some used multiplying….some used trial and error.

We stacked cups in the end to verify that our math was correct.

Most of us had calculated pretty accurately!

## Sky scrapers

Today’s challenge has been an open question about a city plan. In the 4×4 square grid there are buildings that are either 4,3,2, or 1 story, but only one of each height in each row or column.

The numbers on each side represent the number of buildings that can be seen from that vantage point.

We looked at different strategies for solving the problem, and how to use manipulative like linking cubes to help us.

With practice we got pretty good!

When faced with challenging problems, we have choices….we can give up and say “it’s too hard”, or we can keep trying….looking for new strategies, talking it over with other people, or sometimes just diving in and using trial and error.

Some of us wanted an extra challenge and worked on a 5×5 grid!

We looked at strategies to solve these problems easily, and had our expert talk us through the process.

## Representing 10

Today’s intro challenge was to show 10 in as many ways as possible, and there were some impressively creative methods shown!

We can count out 10 things individually, or put them in an array, like the business cards.

Here’s a different array, a 2 by 5 array.

Some used money, showing adding and subtracting.

Some used dice to show how to make 10.

And of course, everyone’s go-to manipulative for “10” is hands!

We also even had a push up representation!

We used our skill to decompose numbers and add and subtract, and also to help us when we multiply big numbers using the area model.

There is help available at school on Wednesdays in the library after school from the HYPE tutors from Queen’s. There are also volunteer and paid tutors available.

## What questions can we ask.

Today we had 3 red cups and 2 white cups on each table. The goal was to ask questions. We came up with long lists of questions that we could answer, or questions that we were wondering about.

Some of us focussed on comparing the two cups, some calculated volumes and others calculated surface areas.

Some of us played the cup game and then we got down to business….

Some of us stacked the cups, and figured out how many cups we need to make a stack as tall as the tallest group member.

We finally worked on the big intense challenge: if white cups stack from the desk, and red cups stack from the floor, is there a magic number of cups that would create equal towers?

## How tall is the school?

We used clinometers to determine the angle of elevation and calculate the height of the school.

Some of us used a level app instead.

Everyone needed to measure the distance to the school as well.

We also used shadows and similar triangles to determine the height of people and other tall items . We compared the shadow length of a meter stick to our shadows.
