Multiplication and Division (2) - Divide 2-digits by 1-digit (remainder) - Presentation

In the mathematics curriculum, students are introduced to the concept of division with remainders. A particular lesson focuses on dividing two-digit numbers by one-digit numbers and understanding what a remainder is and why it occurs. The lesson begins with a discussion aimed at defining a remainder and exploring the reasons behind its occurrence in certain division calculations. The teaching slides guide students through a step-by-step process: first building the number to be divided, then dividing the tens, and finally dividing the ones. For example, when dividing 86 by 4, students learn to first divide the tens (80 ÷ 4 = 20) and then the ones (6 ÷ 4 = 1 r 2), resulting in 21 remainder 2.

Further activities encourage students to apply this division method to different numbers, including those that require exchanging for ten ones before sharing. The lesson also incorporates reasoning exercises where students must analyse and discuss the accuracy of division statements, such as whether 65 divided by 3 leaves a remainder of 2 and if it is indeed two away from a multiple of 3. Additionally, students are challenged with problems that involve sharing items among a group and determining the number of items left over. Independent work includes using place value counters to solve part-whole models and filling in the blanks to complete calculations. A final discussion prompts students to consider the relationship between the divisor and the highest possible remainder, fostering a deeper understanding of division concepts.
