CanDo21 Mats - 3x7

The CanDo21 Mats are a series of engaging mathematical exercises designed to strengthen students' understanding of various mathematical concepts through a variety of problem-solving tasks. The 3x7 mat focuses on deepening knowledge in several key areas, including place value for both whole numbers and decimals, as well as fractions. These exercises encourage students to explore the relationships between numbers and to apply their knowledge in different contexts, such as identifying neighbour numbers and understanding the effects of doubling or halving.

One of the tasks challenges students to apply their understanding of basic multiplication and division facts, such as knowing that 21 divided by 3 equals 7, to more complex problems, like determining whether 30 times 70 is an odd number. Students are prompted to draw connections between simple and more advanced calculations, using arrays and number lines as visual aids. They are also tasked with deriving new facts from known facts, such as using the multiplication fact 3 times 7 equals 21 to solve related problems. Real-world applications are presented, such as calculating how much money Ella spends on sweets from her savings, or figuring out the total number of stickers Billy has collected. These exercises not only reinforce mathematical fluency but also develop critical thinking and reasoning skills.
