Pupil outcome: I can use my knowledge of non-linear relationships to solve problems. Key learning points: - If you can spot a sequence, it is possible to predict behaviour. - By predicting future behaviour, you can plan how to react. -...

Pupil outcome: I can appreciate that not all sequences are linear. Key learning points: - You can identify different types of sequences. - If there is a common difference, the sequence is arithmetic. - If there is a common ratio, the...

Pupil outcome: I can appreciate that there are other number sequences and the limitations of only seeing a few terms of a sequence. Key learning points: - There are more sequences than the ones seen so far. - A numerical sequence is just...

Pupil outcome: I can use my knowledge of algebraic manipulation to solve problems. Key learning points: - Quadratic equations can model real-life situations. - Solutions would need to be interpreted in context. - The difference of two...

Pupil outcome: I can express percentage shaded from shapes within shapes. Key learning points: - You can express a number as a fraction of another and therefore as a percentage. - If you have two areas, you can express one as a...

Pupil outcome: I can plot the graph of a special number sequence. Key learning points: - Visual representations of a sequence can help with identification. - Special number sequences can produce interesting graphs.

This video explains what triangular numbers are and the patterns associated with them. Two puzzles are at the end of the video.

The Handshake Puzzle: a classic mathematical puzzle coming from the topic of combinatorics, this will help develop problem-solving skills. This video provides a demonstration of how to solve the puzzle and asks learners to generalise...

This video explains how to find the nth triangular number, including a visual demonstration. Practice questions are at the end of the video.

The video introduces viewers to three common types of sequences: triangular numbers, square numbers, and cube numbers. The presenter explains how each of these sequences is derived from specific geometric patterns and provides examples...
