Multiplication and Division - Correspondence Problems - Presentation

In a set of engaging teaching slides focused on multiplication and division, students tackle correspondence problems that require a blend of systematic thinking and mathematical skills. 'Systematic' refers to a methodical approach that ensures all possible outcomes are considered and accounted for. For example, one activity presents a scenario where an ice-cream van offers five flavours of ice-cream and two types of toppings. Students are challenged to calculate the number of different combinations that can be made. They must complete a multiplication sentence to represent these combinations, reinforcing their understanding of how multiplication relates to real-world situations.

Further activities deepen the students' problem-solving abilities, such as Rosie's coin combinations, where they explore the possible totals from different selections of coins. Another scenario involves meal choices in a school canteen, where students must use a systematic approach to determine how many different meal combinations can be created from two starters, four mains, and three desserts. They learn to represent these combinations using multiplication, and are also challenged with reasoning questions that explore variations in meal combinations. Additionally, a comparison of T-shirt and shorts combinations between two characters, Zach and Malachi, illustrates that different quantities can yield the same number of combinations. Independent work encourages the use of tables, codes, and physical objects like coins to find all possible combinations, fostering a comprehensive understanding of correspondence problems.
