#### Times Table (multiplication) games. A complete set!

This is a fantastic set of resources for practicing times tables. They are great for quick activities at the start of lessons or in quick maths slots. The children will role two dice and add the digits together. They will then multiply this by a given times table and place a O or X on the corresponding square. The aim of the game is to get 4 in a row. Children are able to block each other if they happen to role the number required. Game can be played in twos, however alternative versions are possible such as three in a row with three or four children using a different colour pen each. An excellent, fun way to revise times tables!

#### Finding factors: 20 more difficult short investigations for KS2

The principle objective of this activity is to teach systematic thinking, in this case to test numbers chronologically with their factor partners up to the square root to ensure that there are no factors missing, and they are identified as quickly as possible. It also provides opportunities to consolidate knowledge and understanding of times tables, square and prime numbers, mental strategies for calculating division, and the efficiency of using divisibility rules. The sheets can be completed by hand or electronically on a PC or tablet. The sheets can be used as homework, or as a time-filler to occupy more able children. It is also an exciting and popular task when used as a daily warm up in the form of a race. The race ends when a child finds the full solution, with merits for the winner and runners up. With a robust group the pupil sheets can be abandoned and the task completed on individual white boards, so the children are not prompted with the correct format and number of factors. When the number of factors is high you will find children calling time when they are a pair or two short, and having to go back to the drawing board; this all adds to the excitement. The pack contains a set of twenty sheets at the higher level. Two packs at a less challenging level of difficulty are available either separately. There is also a related scheme of work that can be purchased separately.

#### KS3 Mathematics Starter Bundle

This is a collection of 8 different resources and approximately 60 different Excel tabs. I use these as a premise for my starters with a mix of abilities from year 7-9. Each worksheet is differentiated, so you can give students varying sheets, or request they work from varying sections of the interactive whiteboard, whilst still providing them with the same answers. They foster a calm start to the lesson, and students always seem excited to learn when the lesson is started in this manner. The addition pyramids contain a self-check tool, so children can usefully self mark. The multiplication grid generator, includes an exciting ‘challenge’ sheet in which students have to work backwards to work out the row and column headers (using similiar skills to Sudoku). In addition to this the Cross number, and the times table grid excitingly contain a magic number extension. This involves students having to collate their answers, i.e. summing certain values, to obtain a magic numbers and perhaps win a small prize (sticker, or sweet, or just simple praise). Please review if you found helfpul.

#### FIFA World Cup 2018: The Ultimate Bundle

Can you feel the excitement brewing for the FIFA World Cup 2018?!? My class cannot stop talking about the World Cup lately. This has driven me to make lots of resources based on the event.
