This Year 3 100s 10s 1s 1 activity uses a range of varied fluency and reasoning and problem solving questions for your children to get to grips with the Hundreds, Tens and Ones step. There are a mix of visual representations, such as Base 10, as well as numerals and worded problems to solve. It's got everything! Just to really round it off, there is an answer sheet supplied, which you as the teacher can use or, to save time, which can be used for some self marking!
