Properties of Number 
The two activities shown here are designed to develop an understanding of number properties. The first activity, shown left, uses a Venn Diagram with two loops and one set of number cards. The objective is to place each of the ten number cards in the appropriate spaces and then to record the results. There are four questions on this page, and it is easy for you to add your own, in the same format. This activity is aimed at Year 4 or Year 5, but could be used with Year 6 children as an introduction to the activity below. 

The activity shown on the left is a development of the first. This activity requires 2digit answers made from one set of number cards. There are many different answers to the questions on this page and a very good extension is available by asking children to find additional solutions, or even to prove that they have them all. The diagram on the left shows a sample from the solution page to illustrate just one way of solving this problem. Click to get both activities and an answer sheet There are two sizes of work mats and property cards. The small size is based on one sheet of A4 and is designed for one child working alone. The larger size is based on the twopage Venn Diagram and is more suitable for groups or pairs. The same small number cards are used for both activities.
