David Flynn @dpfl.bsky.social · 14/12/2024Maybe you could try some open number line stuff with division? And then revisit it when you get to fractions. I put together this task with 24 (which is nice for connecting to 3rd grade denominators!) You can use the first task during division, and then try a similar task during fractions. 120
David Flynn @dpfl.bsky.social · 14/12/2024Puzzle for 4th Graders: Using Base 10 blocks, put together 1 hundred-piece 7 ten-pieces 12 one-pieces to make a rectangle. What are the side lengths of your rectangle? Puzzle for #iTeachMath #EduSky folks: What are the considerations in number choice that make these puzzles unique vs. non-unique? 4142
David Flynn @dpfl.bsky.social · 27/11/2024As a follow up to this Dot Puzzles. I was thinking about how we can use this same set up with fractions in 3rd Grade. Here's a very rough mock up of a puzzle format: #iTeachMath #MTBoS #mathstoday 162
David Flynn @dpfl.bsky.social · 25/11/2024Connect 4 dots to make a rhombus. #iTeachMath #MTBoS #mathstoday 3222
David Flynn @dpfl.bsky.social · 25/11/2024Cool question. I’d not thought about that before and my first instinct was to look for right triangles that made a tangent to a circle. But then playing round on @geogebra.org let me see an easier example. 100
David Flynn @dpfl.bsky.social · 15/11/2024I’ve had a lot of conversations recently about how to keep geometry interesting in 3rd grade. I’m super excited for students to try these Right Angle Mazes. Trace a path from the start to finish using only right angle turns. #ITeachMath #ElemMathChat #edusky 1446
