Gridlocks revision game for KS3, KS4 and KS5

For some variety in your revision you might like to try gridlocks which is a unique way to bolster some key terms and ideas. There are topics suitable for all age ranges and is ideal for those who like all thing Su Doku or problem solving.

First of all, you need to select a topic in your age bracket: Level 1 (11-14), level 2 (14-16) or level 3 (16-18).

In this example is level 2 acids. First of all, you need to match up the terms to the correct definitions. In this example, you have to match up the acid names to their formula and also to a salt formed when in reacts with sodium hydroxide (an alkali). This will act as a reference tool if you get stuck on the puzzles.

Secondly you will be given three 'Su Doku' style puzzles to organise the different fields, in this instance we are using an example with the name and formula of the acids. The hydrochloric acid name cannot go in the same row or column as its formula, which in this case is HCl. 

Post your times below to compare the tougher topics.
