Mastery in maths - year 5 rounding fluency, reasoning and problem solving questions

The red level of challenge is what I bought it for and I was very disappointed to find the numbers were to 1000 rather than the 100000 Year 5 should be working with. It states Year 5, however the red challenge is low for the Year 4 objective and does not touch the Year 5 one. A total waste of money as it has been missold.
