Powerpoint containing 3 part lesson on expanding brackets and solving equations (Level 5/6). Covers simple expansion and collecting like terms (unknowns on 1 side).
Thanks to other TES users for some examples and questions.
Make trial and improvement fun and also get pupils to practice writing expressions rather than just get them to follow a process.
Pupils are challenged to find the missing lengths of the characters in the video game 'Thomas Was Alone' using Trial and Improvement.
EDIT: Updated with answers.
Thank you to TES user Daniel Burke for the zooming (http://www.tes.co.uk/teaching-resource/Trial-and-Improvement-6277974/) and the starter questions.
Pupils required to match quadratic equations to graphs by factorising.
Pupils to discover the relationship between solutions by factorising and the intersect with the x axis.
Does not require completing of the square to find turning point but this could be an extension activity.
Comes with powerpoint that can be used to highlight teaching points. Fits into a series of lessons on expanding and factorising.
Presentation and worksheets to scaffold an investigation as to whether we can "predict" the lottery.
Starter: Multiplication (to work out total balls drawn since start of lottery)
Task 1: Completing tally and using it to calculate relative frequency of each colour.
Task 2: Group work. Using the sample of the first 7 draws to predict the results after 59 draws (up to end of 1995). Each person completes 1 table.
Task 3: Plot the colour coded columns onto the part completed graph. Again, each person has their own graph and can peer assess easily.
Task 4: Discussion of whether we can predict the draw for 6 January 1996 now. Reveal numbers to bring to conclusion.
Raw Excel provided.
A lesson for my low ability year 7 supporting them to understand substitution in real life context of phone contracts. Use of calculator encouraged. High ability stretched to write their own formulae given new contract conditions.
Excel provided if you want to change details and work out answers quickly. Could also be a separate activity for higher ability pupils to make their own Excel.
