KS4/KS5 maths convergence investigation

KS4/KS5 maths convergence investigation

This investigation (includes teacher notes and worksheets) is suited to very able KS4 groups and those in KS5 studying Maths. It covers the topics of convergence, subject of a formula and even can be expanded to iteration for more advanced learners. Pupils are given a starting value of a sequence, which they multiply by 3, add 10 to then and finally divide by 4 to generate the next term in the sequence. They then multiply this value by 3, add ten to it and divide by 4 to get the next term and so forth, generating the sequence in an iterative manner until the sequence converges. The goal of this investigation is to find a relationship between the initial starting value of the sequence and that which it converges to. This can be explained in a satisfying algebraic way using subject of the formula although pupils may offer other alternative explanations.

Erica's Errors - A Level (Year 2) Bundle

Erica's Errors - A Level (Year 2) Bundle

Erica is struggling with many aspects of the A level mathematics course and needs help from your students. What you have here is 17of her homeworks, each with mistakes in solutions which your students need to find, correct and explain where Erica has gone wrong. These are purely designed to generate discussion and to allow students to demonstrate their understanding, whilst also allowing them to show their own methods of silving problems. These are all based upon the new A level curriculum.

Sequences - Required Skills, Examples and Investigation

Sequences - Required Skills, Examples and Investigation

A series of four worksheets to give some background algebra, do plenty of examples finding a limit, then for advanced pupils go on to find a general formula for a linear sequence. If you follow this through you will be able to instantly work out the value of the 50th term of u_n+1 = 0.4 u_n +3 (for example). The four worksheets are: - Indices (practice on this) - Algebra (rearranging formula) - Sequences (standard questions on finding limits, and graphing the results) - Investigation (putting it all together to get a general formula) All provided with full solutions.

Can you crack the code? Further maths revision challenge - perfect for new spec problem solving

Can you crack the code? Further maths revision challenge - perfect for new spec problem solving

For these lessons, I have a wooden box which I fill full of goodies (fruits, sweets etc). I then have a large metal chain wrapped around the box with a colourful padlock on (all of which builds the tension...). The aim is for the students to work away in pairs to crack the code! If you don't want to purchase the box etc, the worksheet works perfectly well on it's own. Note: the solution for this worksheet is 6452. This worksheet is a real challenge for your KS5 students - perfect for the new A Level demands.

Colouring by Annuities - Obama, solve for PV, FV, & Interest (30 sheet mosaic)

Colouring by Annuities - Obama, solve for PV, FV, & Interest (30 sheet mosaic)

Highly Engaging!! Each worksheet represents a small section of the big picture! The end result will look spectacular hanging up in your classroom :) INVOLVED: Each worksheet has 3 questions each of: • Find future value • Find present value • Determine total interest earned • Determine total interest paid It's simple! 1. Calculate the answers. 2. Colour the squares. 3. Cut out your section. 4. Combine with the class! Students complete the problems to decode the colour key, then use it to colour their section of Obama mosaic. High school kids like colouring too! Their curiosity and desire to see the big picture come together will keep them working and helping each other! INCLUDED (.pdf and .docx files): ->Complete class set of 30 worksheets, that combine to create the Obama mosaic. Sheets contain the answers scrambled so students can monitor their own understanding. ->Complete answer keys all worksheets. -> Colour solution and coordinate guide for the mosaic. ->Each worksheet contains 12 problems. Ontario Curriculum: This is great for MAP4C, or MCR3U. All my "Colouring by..." math mosaics use the standard colours found in a Crayola 24 pack of coloured pencils. For best results, use the exact colour name match. Maybe a class set of pencil crayons would be a fun departmental purchase? :) I'd love to hear from you! Leave some feedback through Tes about how this went in your classroom, or email me at calfordmath@live.ca
