Code Breaking in Year 3!

Year 3 have been challenging themselves in maths recently by attempting to crack some tricky codes! They have been applying all of their mathematical skills, including their times table knowledge, to solve the puzzles!

After supporting each other and using all the resources available to them, they succeeded in cracking the codes!

Great work guys! I think you will all make some excellent detectives or spies one day!

Can you demonstrate your problem solving skills and solve this challenge at home?
