Students explore patterns and sequences and develops estimation, counting, addition, subtraction and multiplication skills with whole numbers and decimals. The objects introduce algebraic thinking in an engaging, non-threatening way, using words and visualisation rather than symbolic notation.
- Using a number grid, students estimate the answer to a word problem (the jump plan). They watch a frog (the Hopper) dynamically complete the jump plan on a number line and observe the pattern produced on the number grid. The jump plan is a rule or expression that promotes algebraic thinking.
- Each completed jump plan is shown to the students in three ways: as the written rule, on the number line and highlighted on the number grid
- Following each jump, students select the problem, from a choice of three, which matches the jump pattern they have just used
- In the Hopper subset of learning objects there is additional scaffolding where the patterns are represented on non-numerical grid patterns to assist visualisation of the pattern.
