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.

An advice rubric provides interpretations of student responses and corresponding teacher strategies to assist students to overcome specific misconceptions. Printable classroom resources and teacher notes are provided.
