Addition, Subtraction, Multiplication and Division - Multi-step Questions - Presentation

In a series of engaging and challenging activities, students are invited to tackle multi-step problems involving the four core operations: addition, subtraction, multiplication, and division. The lesson's structure encourages students to decipher the meaning of 'multi-step' and apply their understanding to various scenarios. For example, one activity involves deducing the next page number in a book based on the sum of two visible page numbers. Students must use division and logical reasoning to find that if two consecutive pages sum to an odd number, the next page number will be the higher even number following the pair.

Further activities delve into real-life applications of mathematical operations, such as determining ages based on given relationships and totals. By setting up algebraic equations, students solve for unknown values, like the age of a character named Tia when given the ages of her companions in relation to hers. Another problem requires students to calculate the remaining number of milk bottles after a series of transactions, challenging them to apply the correct order of operations. The lesson promotes critical thinking and problem-solving skills, as students must identify key information, construct models, and form number sentences to accurately resolve multi-step problems.
