I've used this activity for the past few years, using foam circles from Dollar Tree that I labeled with sharpies and stuck up all over the room.
My ceilings are too high to reach and I felt like that always threw them off. This year I got the bright idea to cut up tissue boxes and use blank yard sale stickers.
I gave them the worksheet with a picture on it too and asked them to make sure the stickers were in the right place. Sadly they were nowhere near sticky enough and repeatedly fell off. Now I feel like I need some laminated circles and hot glue them to the box. Any better suggestions?
This was the last activity before their quiz. After like 6 DAYS of point, lines, and planes, the grades were still bad. I think the highest was an 86% and the majority of the class was between 50%-75%. Why is this so hard? It's like the more time I spend, the worse it gets. I hate that it's the first lesson of the year because it drags on forever, they get a bad grade, and then they decide that geometry is too hard and they're going to fail.
Moving right along....
I used this 'number line' to introduce absolute value equations.
Questions I asked:
- What is something weird or unusual about this diagram?
- What is something familiar about it?
- What kind of math thing could it represent?
- If the pink magnet was a number, what would it be?
- What is three magnets away from the pink magnet?
- Why are there two possible answers?
- What is two magnets away from the star?
- What could the magnets represent?
- Can you have a negative distance?
- What is the definition of absolute value?
This was done in about 2 minutes and then we jumped right into INB notes.
And here's a fun video of us playing Grudge Ball but I call it The X Game because there are no balls and there are X's.
Any time they run to the board, it's a win. =)
