Hooks

  • Transum - This website is useful for starting lessons or, as breaks in between a lesson
    • My colleague Cindy highly recommends Countdown and Ancient Mysteries for lower ability classes
  • Which One Doesn't Belong?
    • Each prompt features four objects (such as shapes or numbers)
    • Any of the four objects could be said to not belong, providing room for discussion
    • Encourages students to present mathematical arguments and demonstrate reasoning

Exercises

  • Mathspace: needs no introduction, used in most classrooms, provides individual-targeted exercises digitally
  • Freefall Mathematics: worksheets and ebooks - many schools have a subscription
  • Numeracy Ninjas: Practice questions for numeracy
    • Builds on primary and Year 7 skills such as times tables, time telling, place value, etc.
    • Recommended by my colleague Madushan

Lesson Plans

Games

Geometry

  • Pythagoras Theorem: Intuition and Applications
  • Liquid Pythagoras Theorem: Visual model of areas of right triangle sides Liquid Pythagoras
  • Pythagorean Stack: Extension activity for Year 8
    • This activity comes from Equation Freak Blogspot
    • My colleague Paige notes: everyone had different answers to the final side value, including us teachers. It was great to see how using certain values at certain decimal points can have long-term effects on a final answer.
  • Grok Learning: Programming with Python
    • My colleague Alex recommends this resource with the following descriptors
    • It introduces programming for year 7 students
    • Can be easily integrated in the Measurement topic
    • One option is python programming, the other option uses block-style click-and-drag programming.
    • Note: this is a paid resource but can be shared by the whole school, including coding activities and some courses used by the DT department
  • Dance Dance Traversal: Game for Angle relationships
    • Cindy made this activity to teach co-interior angles, corresponding angles, etc.
    • Year 7-8
    • Fun team activity, requires some open space
    • Based on the popular game Dance Dance Revolution

Manipulatives

  • Four Card Permutation: interactive (GeoGebra)
    • shows how permutations are limited by choices and thus intuition for the formula n!
  • Fraction drawing: whiteboard for fractions, provides pie and rectangular shapes
    • Start with the information icon to the right (i), the interface is confusing without explanation
  • Place value columns: visual depiction of place value with blocks, mimicking a classical teaching prop for primary students
    • can be used to support numeracy
  • Polypad/Mathigon: visualisations and interactive representations in geometry, algebra, fractions, probability etc.

Multiple Topics

  • Gerry Dear Resources for Maths Teachers
    • My colleague Hui Min found this helpful when planning lessons and provided the following descriptions.
    • Contains PowerPoints for some topics in Stage 4 and 5
    • Good starting point and inspiration as to how to teach some topics
    • Particularly good are the transitions included and the design for student engagement
    • Recommended: order of operations, angles of elevation and depression, rates and prime and composites.
  • Corbett Maths
    • Video tutorials, worked examples and exercises
    • Topics covered: geometry, algebra, stats (averages), decimals + lots more
    • Warning: Unsorted, long list
  • Kyle Webb Maths Tasks and BTC Curricular Math Task Sheet K-12
    • My colleague Cindy sent this link of resources based on the pedagogy discussed in Peter Liljedahl's book, 'Building Thinking Classrooms in Mathematics'
    • Activities to teach mathematics through a more critical thinking lens
    • These are aligned with Canadian and U.S. standards, so require a bit more searching.
    • Relatedly: Jojo Ayao provided this powerpoint using the Building Thinking Classrooms model.

Miscellaneous

  • Comparative Tables for Variables
    • Students fill out tables asking them to sketch how function output would change with smaller or bigger values.
    • Prompts intuitive understanding of how change in variables changes functions
    • Tables for Year 7 and Year 12 provided as examples
    • Idea can be used for any mathematical concept where two variables are compared into a graphical or physical representation
    • Encourages students to visualise concepts
    • Paige found this activity sometimes better in competitions, and sometimes in discussions
  • Implicit Differentiation Worksheet
    • Andrew Huang made this worksheet for his Extension 2 class, as a refresher for related rates/differential equations
