This week’s WOW is Maths Starter a Day. This site features a calendar that has links to a different maths problem for each day. The problems are based on a range of maths topics and encourage problem solving skills as they provide JUST enough information for the students to solve the problem. (Can be quite frustrating for some students at first until they start to develop their problem solving skills.)
I have used this in class as an introduction to the Maths lesson and it is also an excellent activity for early finishers. The problems range in difficulty and I would suggest that they are probably best suited to high grade 3 students and upwards.
All problems have the answers and usually some demonstration / explanation of how to solve the problems at the bottom of the page.
