Maths board games

I have accumulated a number of board games where maths is the primary objective. Some are number based and some are logic puzzles.

Number games
Sum Swamp. A simple board with three dice. Two have numbers on them and one has plus or minus. The three dice are thrown, the player solves the sum and then moves forward that many places.

Triolet. A French board game akin to scrabble. Each player has three tiles and uses these to make a sum of no more than 15. No more than three tiles can be used in a sum so placement on the game board can be crucial. Very good for number bonds.

Smaths. The maths alternative to scrabble can be a lot harder. We started off with only plus and minus sums, then added in multiplying and dividing at a later stage. Usually with this game we give up before using all the pieces. However it is enjoyable just hard work on occasions.

Number Quest. A large board is covered with the numbers 1 - 100 in a diamond formation. Each player throws four dice and then uses those numbers to make a sum that adds up to a free number between 1 - 100. For example if the player threw 4, 5, 6. 6 the sum could be 4+5+6+6 or it could be 4X5 + 6X6. We tend to use a timer and then see how many points we can earn in half an hour. You can aim to cover a line or have a continuous link from 1 - 100. Lends itself to different solutions.

Shut the box. The box has the numbers 1- 9 and by throwing two dice the player tries to shut down all 9 numbers. Simple but fun.

Logic puzzles
Tangram. Wonderful to play with and make different shapes. I found a ravensburger set with an entire booklet of ideas.

IQ block. Nine shapes that fit into a sqaure 40 different ways although finding one can be hard enough.

Other games
Blokus. Each player has 21 pieces to place on the board trying to maximise their coverage of the board whilst blocking their opponents. Reminds me of tetris.
