Dots and Boxes. A mental maths strategy game for KS2

Here’s a mathematical variation of the classic game, “Orange Boxes”. A game for two players which is great for developing mental maths skills, adding several single digit numbers.
RULES
Each player needs a different colour crayon or felt tip.
Take turns to joint two dots, vertically or horizontally. When you complete a single square (box), the box is yours. Colour it your colour. The players take turns but whenever a player makes a box they must move again. When all boxes have been made and coloured, each player adds up the numbers inside their boxes. The player with the highest total (not necessarily the most boxes) wins.
