Here are video inputs for each day, along with worksheets for the children to complete. You may choose to print out the worksheet for children to write onto, but it would be even more helpful for their number fluency if they copy out and answer the questions onto a second sheet of paper (as well as saving on your printing!)
The worksheets contain reasoning and problem solving questions towards the end, and at the end of the page there is also a powerpoint with challenge questions to be done across the whole unit (one per lesson).
