If you wanted three equal sized cakes, what size pan do you need?

(I should mention that they were restricted to digits 1,2,4,5, and 8 with no repetition!)

Also, some answers are “better” but require more thinking. When I asked for a fraction close to 45%, one group made 21/48 because it’s a bit less than 1/2, while another reasoned that 45/82 worked as 82 is close to 100. Which is actually closer aside, we appreciated different strategies!

I think it’d work for sure! I framed it as a game for buy-in but it’s really just an open-middle thinking task. Some questions have exact answers, but most require estimating and there might be several answers that are “close enough”. We didn’t actually keep score!

A template for students to line up their digit cards to create a fraction, with a two-digit numerator and two-digit denominator.

My prompt for round ten, written in French. Translated: I want a decimal as close to 15% of 38.00$ as possible!

A game score card, showing students’ answers (the fractions and decimals they created) for each round.

In #MathsToday Gr7s played a game, building fractions and decimals out of a (limited) set of digit cards to meet my increasingly challenging demands. So much discussion, estimating, converting, and evaluating multiple potential answers. They loved the activity and I loved their thinking! #ITeachMath

Example #1: a fox sitting by a bush, made out of coordinates plotted on a Cartesian plane. The instructions for creating the image are written below.

Example #1: a phoenix, made out of coordinates plotted on a Cartesian plane. The instructions for creating the image are written below.

Passed back some art on the Cartesian plane my students made a couple of weeks ago. I was shocked how much some of them enjoyed the task and provided much more detail than I asked for/anticipated. #iteachmath

A bowl of Pad Kra Pao (Thai basil tofu)

Tofu Pad Kra Pao (Thai basil tofu) from Drive Me Hungry. Can confirm this was absolutely easy and delicious. #CookSky #LetsEat

A stack of two books: Cher, the Memoir Part One; and The City and its Uncertain Walls by Haruki Murakami.

As an ardent fan of both Murakami and Cher, today is a beautiful day. #BookSky

Students testing a filter made out of rocks and other materials in a funnel.

Gr 7s spent the period investigating the best materials for filtering some polluted water. Lots of evaluating and revising … #iteachscience

A student plays with a model of human lungs made using balloons, straws, and a plastic cup.

And in science, Gr 8s made a model of human lungs. Great to illustrate the role of the diaphragm in respiration. #iteachscience

A worksheet inside a plastic page protector serves as a game board for students who are scoring points by finding equivalent fractions, decimals, and percents.

In #mathstoday Gr 7s played games creating equivalent fractions, percents, and decimals to consolidate their strategies for converting. Scoring points by creating lines in either (or both) of the two grids added an element of strategy. #iteachmath

Mike in a pink sweater!

Hi folks! I have taught math and science to grade 7 and 8 students for six years and am looking forward to learning from the community here! My personal life and other creative interests may also creep into my posts from time to time. Happy to be here so far! #iteachmath
