It explores the use of triangle numbers and similar sequences Ina range of contexts.ġ.19 Sequences. This section introduces the idea of Triangle numbers including how it can be illustrated using equilateral or right-angled isosceles triangles of dots. The idea behind the book is that teachers can take it into the classroom and use the ideas straight away, annotating as necessary and adding their own suggestions.ġ.17 Triangle numbers. Each idea is accompanied by teachers' notes. This resource is part of a larger resource - Number and Algebra Instant Maths IdeasĮach topic contains a number of questions or activities designed as inspiration for starters, extension questions or probing questions, useful to supplement lesson plans. Quality Assured Category: Mathematics Publisher: Colin Foster Series geometrically explains how to split up a square to show that the sum of a sequence tends to a value of one. Limits, considers what happens to the sum of sequences as the number of terms increases. Pack three explores Fibonacci style sequences, uses tables of differences to find the nth term of a quadratic sequence and I nfinite sequence, and investigates the sums of sequences of fractions whilst the activity. s quidge explains how to produce patterns by combining multiplication and addition, and s taircases begins by explores the generation of triangular numbers before moving on to more complex sequences. Pack two contains the activity Patterns in spirals, exploring the number patterns generated when drawing spirals on dotted paper. More appropriate to this topic are the following activities in packs two and three. The first pack contains relatively simple activities relating to linear sequences. This resource contains three packs of activities increasing in difficulty. Quality Assured Category: Mathematics Publisher: SMILE
