Cakes and Bansho

We started a new art lesson today about Wayne Thiebaud and his cakes. Our artwork success criteria involves drawing a 3D cake with a slice cut out of it and using shading to capture the low light.

Today we practiced drawing the shape of our cakes.

Please look at the Math At Home tab at the top of the blog to see this week's Bansho question. Here are our solutions in order of efficiency. All of our methods would work at finding an answer but some methods would work more efficiently than others.

This group is adding one block at a time and seeing if it fits the problem.

 We started writing out all of the multiples of 3, 4, and 5 but that took too long. One of us thought that 60 would work so we did the multiplication to prove it.

 We used the multiplication chart to find a common multiple of 3, 4, and 5.

We knew the number had to end in a 5 or a 0 because it has to be a multiple of 5. We also knew it couldn't end in a 5 because then it wouldn't be a multiple of 4. After that, we quickly found 60 was a multiple of all three.

Great Bansho everyone!!! Yay us!
