Numeration and place value Interactive Resources: Virtual base ten blocks: Place value activity Help students visually represent numbers and place value. Students are given a target number and drag base 10 blocks onto the paper to represent that number. As students add blocks, a counter at the bottom of the page shows how many blocks are currently on the paper. http://www.learningbox.com/Base10/BaseTen.html Wishball: whole numbers Test your understanding of place value with whole numbers. Receive a starting number, such as 3786, and work towards turning it into a target number, such as 7664. Spin a random digit, choose its decimal place value and decide whether to add or subtract the random digit from your starting number. You can use a 'Wishball' to help you reach the target number. Try to achieve the target with as few additions or subtractions as possible. This learning object is one in a series of ten objects. http://www.scootle.edu.au/ec/viewing/L867/index.html Hopper: whole numbers Help a frog to jump along a number line. Estimate the finishing point on a number line, after adding or subtracting multiples of whole numbers to a starting number. For example, 255+(10 x 4) = 295. Explore the patterns made on a counting grid and number line. Identify counting rules that match the pattern of 'landing spots' on a counting grid. This learning object is one in a series of seven objects. http://www.scootle.edu.au/ec/viewing/L1084/index.html Arrays: explore factors Explore how numbers can be broken up with factors. For example, the number 9 can be expressed as 9x1 or 3x3. Predict the factors of a number in the range 1 to 50. Make an array of equal rows and columns with the number to check its factors. Choose a statement to describe how many factors the number has. This learning object is one in a series of five objects. http://www.scootle.edu.au/ec/viewing/L2060/index.html Factor Game 3-5, 6-8 Exercise your factoring ability against a human or the computer in this Calculation Nation game http://illuminations.nctm.org/Activity.aspx?id=4134 Place value to 100,000 An interactive that requires students to construct a five-digit numeral on a place value chart and then write the numeral.
