Table Splat! (Times Tables Game)

Table Splat! (Times Tables Game)

A game that can be played in pairs, threes or independently. Please note that this game focuses on times tables facts from 2 to 10 to ensure children are confident in these tables before progressing to the 11s and 12s, which will need to be taught subsequently.Children need a 'Table Splat' mat and counters (different coloured counters for each child). Children take turns to turn over a card, revealing a times tables question. The child who is the first to place their counter on the correct answer (whilst shouting 'SPLAT!') can leave their counter on the board. The winner is the player with the most counters on the board once all of the times table cards have been used.Differentiate by choosing the multiplication cards relevant for that child, depending on which times table they are currently working on. *Update: 6s and 9s have been underlined, to avoid confusion.*Save money when bought as part of a bundle.

Hexagonal Numbers (Cross-number Puzzle)

Hexagonal Numbers (Cross-number Puzzle)

This resource consists of a cross-number puzzle whose solution involves the calculation of hexagonal numbers. Geometric diagrams are given for the first few hexagonal numbers. Students will then have to devise methods to calculate larger such numbers.The Teachers Guide outlines three possible investigative approaches to these calculations. One involves generalising using the given geometric patterns. The other two approaches involve investigating numerical patterns which then leads to the construction of a nth term formula. One is through patterns in a difference table and the other involves patterns in the numerical factors of the hexagonal numbers.The answers to the puzzle clues are also given in the Teachers Guide.

Last Minute Maths Arithmetic Paper 2017 SATS Revision. Year 6 - KS2.

Last Minute Maths Arithmetic Paper 2017 SATS Revision. Year 6 - KS2.

A flip chart and SATS style question paper based on the arithmetic paper (paper 1) . Created by a year six teacher (89% maths at and above expected pass rate last year), maths coordinator and deputy head. Used on the afternoon before the 2016 maths SATS tests and updated in 2017. The flip chart allows the teacher to model the mathematics concept with a SATS style question and then gives the pupil the opportunity to use and apply what they have just seen. This is designed specifically for revision purposes as I have found my class sometimes fail to retain certain mathematical methods or struggle to use what they know to figure out what they don't. THIS IS AN ACTIVINSPIRE FLIP CHART

At least 3 lessons worth of material. First lesson goes through Highest Common Factors and Lowest Common Multiples. Engaging nature facts and memorable methods help the learning of these skills. Moves on to understanding prime numbers and what they are. Followed by prime factor trees (prime factor decomposition). This leads into using prime factors to calculate the HCF and LCM using Venn Diagrams.
