A culminating activity where students apply all their skills to solve a "final case" involving multi-step problems and patterns.

Students summarize their learning by identifying and explaining various arithmetic rules and properties they have discovered.

Students solve complex word problems requiring multiple operations, choosing the correct order of steps.

Students represent two-step word problems using equations with a letter standing for the unknown quantity.

Students tackle two-step word problems involving multiplication and division, focusing on equal groups and fair shares.

Students solve two-step word problems involving addition and subtraction, using tape diagrams to represent the situation.

Students practice checking the reasonableness of their answers by comparing their exact results to their rounded estimates.

Students learn to round numbers to the nearest 10 and 100 as a tool for quick estimation in problem-solving.

Students use known multiplication patterns and the distributive property to solve for unknown facts, such as using 5s and 2s to find 7s.

Students explore the diagonal of the multiplication table to identify square numbers and investigate the patterns within them.
