Addition and subtraction within 10 - Number bonds to ten - Presentation

In a mathematics lesson centred around the concept of number bonds to 10, students are encouraged to develop fluency and reasoning skills. The lesson begins with a simple yet fundamental question: can the students count forwards and backwards to 10? This sets the stage for exploring the various combinations of numbers that add up to 10. Through a series of interactive activities, children are presented with visual aids such as fingers and ten frames to help them visualise and understand the concept of number bonds. For example, if Zach shows 6 fingers, students are asked to determine how many more fingers are needed to make 10, and then to express this as a number sentence: 6 + 4 = 10.

Further activities build on this foundation, with children using ten frames to complete number bond sequences and to identify the missing number in a bond, such as finding the unknown addend in the equation 4 + ____ = 10. The lesson also incorporates practical reasoning exercises where students consider real-life applications of number bonds, like Tia having 10p to spend and figuring out the different combinations of items she can buy. In addition, children are encouraged to think critically about the properties of number bonds, discussing whether they always consist of two different numbers or if there are exceptions, such as the bond 5 + 5 = 10. By the end of the lesson, students are expected to confidently identify, articulate, and systematically order number bonds to 10, a key mathematical skill that underpins their understanding of addition and subtraction within 10.
