Addition and Subtraction Facts - PowerPoint

In this set of teaching resources aimed at Year 1 students, the focus is on understanding addition and subtraction facts up to 10. The PowerPoint presentation begins by introducing the concept of addition as combining two amounts together. For example, the sum 4 + 2 = 6 is presented as a basic addition fact, illustrating that when we add 4 and 2, we get a total of 6. It then explains that addition facts can be reversed, showing that 2 + 4 also equals 6, emphasizing that the order in which numbers are added does not change the result. This concept is further reinforced through a series of slides that prompt students to identify related addition facts from given examples.

Subsequently, the presentation shifts to subtraction facts, explaining subtraction as the process of taking away one quantity from another. It presents the subtraction fact 6 - 2 = 4 and highlights that, unlike addition, the order in which numbers are subtracted does affect the outcome. The largest number is placed first to avoid negative results. Students are then encouraged to work out related subtraction facts from provided examples. The interactive nature of the slides invites learners to engage with the material by determining the related addition or subtraction facts for a set of three numbers, thus reinforcing their understanding of these fundamental mathematical operations.
