# KS2, Calculation

**This is another of our clean-and-simple, fun maths games.** It is a 'three in a row' type game with a tight focus on practicing/using multiplication facts.

The game board features a grid of 25 numbers, children work in pairs using different colours of counters and a set of digit cards (2 to 9). They take it in turns to reveal a card, and then put a counter on** any multiple** of that number on the board. **Read more »**

**Here's another deceptively simple maths game which delivers a powerful 'learning' punch. **We first used this one at the end of last year and it was very popular! **Read more »**

**Just time for one more fun resource**. Four cross-numbers with clues that enable children to practice their mathematical skills (calculation), knowledge (number properties) and their reasoning and organisational skills.

**This is a follow-up to our popular Calculator Activity-1.**

While that original resource focused exclusively on Addition, this one helps children develop their understanding (and accuracy) when reading written numbers and calculating with **both** addition and subtraction.

**This is a great way to get children discussing the mental strategies they use when calculating**.

The idea is that the children have to follow a series of instructions to arrive at an unknown number. The image on the left shows a chain of number operations. The starting point is **2**, to which 4 is added (making 6), this is then multiplied by 2 (giving 12), divided by 6 (making 2) then, finally, 1 is added (to end with 3). **Read more »**

**This is a quick way to demonstrate some ‘mathemagical’ powers** – it also serves a useful purpose in that it will give children an entertaining opportunity to make use of investigative/problem solving skills.

You show the children a set of ‘raffle tickets’ each of which features a small identification number and a main four-digit ‘raffle’ number. Ask a child to pick a ticket at random, to show it to the rest of the class and to tell you only the small identification number. **Read more »**

**Here's another 'why didn't I think of that' moment - a stunning place-value and calculation activity (well, we think it's fairly stunning).** I had nearly forgotten about it until we started looking through some old work files in the garage. **Read more »**
