Addition and subtraction - Know your bounds - Presentation

The presentation "Know Your Bonds" is an engaging and interactive set of teaching slides designed to help students understand and find number bonds in the context of addition and subtraction. The slides prompt students to recall what number bonds are before diving into various activities. For instance, one activity displays a set of counters and asks students to identify addition sentences that sum up to the total number of counters, which in this case is six. The activity gradually reveals all possible combinations that make up the number bond to six, such as 6 = 1 + 5, 6 = 5 + 1, and so on, until all pairs are identified including 6 = 0 + 6 and 6 = 6 + 0.

Further activities challenge students to systematically find number bonds to other totals, such as 2 and 4. The slides guide students through each possible combination, reinforcing the concept that a number bond is made up of two numbers that add up to a given total. Additional exercises involve identifying the value of objects, such as balloons and balls, to further apply the concept of number bonds in practical scenarios. To consolidate learning, the presentation concludes with independent work where students are tasked to find number bonds, add correct number sentences to a table, complete number bonds with missing numbers, and calculate the value of different shapes.
