Maybe gradually removing parts and asking they think goes in the blanks.

Maybe 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.

Puzzle 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?

Yep, sorry! This oughta work:

As 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:

This is my slightly more ludicrous example.

Connect 4 dots to make a rhombus.

Cool 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.

I’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.
