Place value - Counting in 5s - Presentation

The presentation focuses on reinforcing the concept of place value through the activity of counting in fives. The first activity prompts students to calculate the total number of fish by determining how many fish are in each tank and the number of tanks, and then multiplying these together. This activity not only reinforces counting in multiples of five but also applies multiplication skills. The second activity follows a similar structure, where students count the number of marbles in each jar and the total number of jars to find the total number of marbles. These activities are designed to strengthen students' fluency in counting and their understanding of place value.

Further activities challenge students to identify and continue patterns when counting in fives. One task involves a grid of numbers up to 50, where students are asked to highlight the pattern that emerges when counting in fives and to explain why this pattern occurs. Another activity presents a number line where students are required to complete the sequence by counting in increments of five. Through these exercises, students develop their reasoning skills by justifying their answers and identifying numbers that do not fit the pattern of counting in fives, such as recognizing that 26 is the odd one out in a sequence of numbers typically counted in fives. Group discussions and collaborative tasks further enhance their understanding of place value and the patterns formed when counting by multiples.
