These presentations follow on from Charlie's presentation at the 2018 November Conference
MatteLIST Mathematical activities with challenges that suit everyone!
Slides
Mathematical Reasoning, Justification and Proof
Not just for the older students
Cryptarithms
Tapping into students' curiosity
The Number Jumbler followed by
Always a Multiple?
Assuming students can/will think
Mixing Lemonade > Limonade i glasset
Requiring students to think strategically
Missing Multipliers
Collaborating - convincing yourself, convincing a friend, convincing others...
Dozens > Delelighet
Requiring students to step back
Make 37 or What Numbers Can We Make? > Hvilke tall kan vi lage?
Building on previous ideas - Low threshold, high ceiling tasks
Take Three from Five > Velg tre av fem tall
Requiring awareness
Route to Infinity
Encouraging students to test ideas
Odds and Evens
Celebrating multiple strategies
What's it Worth? and Fruity Totals
Building on conjectures
Summing Consecutive Numbers > Summer av påfølgende tall
Offering support but still expecting students to think
Kite in a Square
Elegant proofs
Geoboard > Vinkler i sirkler
Marbles in a Box > Tre på rad i en boks
Magic Vs and Magic Letters > Magiske bokstaver
Strike it out > Stryk ut tall
Got It > Først til ...
Add to 200 > Legg sammen til 200
To create a better society, first we must imagine it. But then we must act.
