The Base Blocks addition and subtraction activities on this page are fantastic! Allows you to group or split the blocks in each column to rename them eg ten 1s and one 10s
Help a town planner to design a site plan for a school. Using a 10x10 grid, design areas for four regions (library, car park, lawn and canteen) based on the percentages given. Assign the area for an additional two regions, using percentages of your choice. Use a number line to indicate the equivalent fractions for two regions. This learning object is one in a series of two objects. The series is also packaged as a combined learning object.
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.
good website that students can visually see groups of fractions. It has explanations for equivalent fractions, reducing, improper and proper, multiplying and addition of fractions.
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.
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.
Help a girl to throw her ball through a hoop. Build two fractions to make a total of one whole. Complete the denominator of a fraction (at least one fraction may have a fixed numerator). For example, work out how many tenths can be added to three-fifths to total one whole. Look at fraction bars and a number line to compare the two fractions and their total. This learning object is one in a series of seven objects.
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.
