Guide students to discuss the algorithm or process that they would use to find a value in a sorted list and how that would be different in an unsorted list. Help them to recognise that the best way to search the sorted list is to do a binary search: it does matter what order they actually look at the books.

Students are provided with a scenario and asked to determine which amounts of postage is it impossible to make using only five-cent and seven-cent stamps? The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.

In this activity, students filter different substances through a plastic window screen, different sized hardware cloth and poultry netting. Their model shows how the thickness of a filter in the kidney is imperative in deciding what will be filtered out and what will stay within the blood stream.

Problem of the Day resources are for use of spiral content review in Math class. Each resource has a week worth of problems, one for each day of the week. This allows for quick, re-teachable moments of standards your students may not have mastered the first time around, or that they need additional practice with.

This video has been created by NCDPI. It provides tips for integrating reading within the math block.

In this lesson, students will create and extend patterns, write algebraic expressions to model rules or patterns, and evaluate algebraic expressions for a given value.
