Factors and multiples worksheet

A comprehensive worksheet from KS2Gems, designed for Year 4 students, breaks down the concepts of factors and multiples into engaging activities. The first four activities focus on factors. Activity 1 uses whiteboards and pens, where the teacher provides two numbers and students must write down other numbers that include these as factors, with an option to add a timed challenge. Activity 2 encourages children to determine which number between 1 and 20 has the most factors, promoting the use of strategies such as eliminating prime numbers first. In Activity 3, each child receives a digit card from 1 to 9, and when a number is called out, those holding a factor of that number display their card. This activity includes swapping cards for variety. Activity 4 involves stating a number and asking the children to list all its factors, ensuring they understand how to verify their list is complete.

Activities 5 to 8 shift the focus to multiples. With whiteboards and pens at the ready, Activity 5 sets a challenge for students to list as many multiples of a given single-digit number as possible within a minute. Activity 6 follows a similar pattern but asks for common multiples of two stated single-digit numbers. In Activity 7, children are given two-digit number cards and must identify if their number is a multiple of a stated single-digit number, displaying their card if it is. Lastly, Activity 8 asks students to write the first five multiples of 99 and to observe and continue the pattern, encouraging pattern recognition and prediction skills. The objective of these activities is to help students identify multiples and factors, including all factor pairs of a number and common factors of two numbers, fostering a deeper understanding of these fundamental mathematical concepts.
