Students work on practical problems in which the complexity of computations extends to include addition and subtraction of three-digit numbers, multiplication by single digits, and division by a single-digit number using arrays.
Fun number based games- particularly popular with the boys in my class. Games work on division, addition, multiplication and subtraction of simple numbers. When you select a game, make sure select- the create game tab- which will just take you to a new game instead of an existing one.
Put blocks (or balls) into the cups on the scales to make them balance, using the number rules A = B + C and A + B = C + D. Use your knowledge of addition and multiplication to help you work out how many blocks you need in each cup. Finish the number sentence to show an equal number of blocks on each side. This learning object is a combination of three objects in the same series.
a Flash based website with interactive manipulatives that students and teachers can use to introduce or reinforce maths concepts. It is suitable for students from Kindergarten to Year Eight.
This site is very simple to use (mostly drag and drop) and requires very little preparation.
You simply choose a background from the collection of Game Boards, Story Boards or Work Mats. Work Mat options include place value mats, tens frames, graph paper, algebra tiles, in and out equation tables, blank calendars, number lines and number charts.
A good game for negative numbers and mathematical thinking. This game is for two players - you can use the interactivity below, or you could draw a number line on a piece of paper and find a counter to use. In both cases, you will need two dice. Decide who is Positive and who is Negative. Positive moves from left to right and Negative moves from right to left. Take it in turns to throw the two dice and add the scores then move that number of places in your direction. If the counter reaches −13, Negative has won. If the counter reaches 13, Positive has won.
