A spatial pattern involving the area of a shape is represented by a table and a diagram. Students describe the rule in words and as an algebraic expression.
In this task, students look for patterns in electron arrangement in the periodic table. They use their ideas to place missing elements in the table, answer some questions about the patterns, and use the patterns to predict the properties of some elements.
Students convert heights of a building into the percentage of the given total height, explaining how they solved some conversions. Assessment focus is on how they calculate these heights and what strategies they use.
