Place Value within 50 - Count in 5s 2 - Presentation

The lesson titled "Count in 5s" is part of the Place Value series aimed at helping students understand numbers within 50. Throughout the lesson, students are encouraged to identify and continue patterns by counting in increments of five. The initial task asks them to extend a given sequence (5, 10, 15…) and observe the pattern that emerges when counting in 5s. This is a fundamental skill in developing their numerical fluency and understanding of place value. Subsequent activities involve practical examples, such as counting fish in tanks and marbles in jars, to reinforce the concept of counting in 5s, with each tank and jar containing five fish or marbles respectively. Students are then asked to calculate the total number of fish or marbles by multiplying the number in each container by the total number of containers, thereby practising their counting and multiplication skills.

Further activities include continuing the count in 5s on a 50 square grid, where students can visually identify the pattern of numbers ending in 5 or 0. They are also tasked with completing a number line by counting in 5s, which helps them understand the sequence and intervals between numbers. The lesson incorporates reasoning exercises where students must apply their knowledge to determine if a statement is correct, such as whether making eight flowers with counters would require 38 or 40 counters. They also identify the odd one out in a sequence, reinforcing the concept that when counting in 5s, numbers should end in 5 or 0. Group activities and independent work are included to encourage collaboration and individual practice, with tasks like colouring in multiples of 5 and completing number lines. Discussions prompt students to articulate their understanding of patterns and predict which numbers will appear on a number line when counting in 5s.
