Just in case I forget, Dan’s activity on factoring trinomials by creating a headache – it’s a good one that I’ve used a couple of times and seems to spark enough interest.
Jon Orr’s introduction of factoring is a bit different, but may still have some helpful content?
A collection of activities and resources that can be used for perimeter and area discussion/lessons, such as:
- Perimeter Jumble by Jon Orr, raising questions about area and perimeter relationships
Not that it’s every really pi day in Australia, but in case I want to run some activities sometime…
- I can just eat circular food and measure things to discover pi like I did with my college class once
- I could have them write pi poetry
Here are some links to resources / puzzles / activities etc. that I have found useful doing work on congruent triangles.
- Multiple lesson plans to follow including some activities on proofs
- Picture puzzle to use for cutting shapes into two congruent shapes
- Also something from Fawn I haven’t tried yet here.
Came across this site with some images/discussion about explaining and understanding ideas around dividing fractions.
