Addition and subtraction - Find and make number bonds - Worksheet

The "Bonds to 100" worksheet is an educational resource aimed at enhancing children's fluency and precision in addition and subtraction through the use of number bonds. The National Curriculum objective for this lesson is to recall and use addition and subtraction facts up to 20 fluently, and to derive and apply these facts to numbers up to 100. To aid in the teaching of this lesson, differentiated worksheets, teaching slides, and 10 frames are utilised as key resources. The vocabulary for the session includes terms such as addition, subtraction, facts, number bonds, multiples of 10, 10 frame, and patterns. Teachers are encouraged to emphasise the multiples of 10 up to 100, drawing parallels between single-digit bonds and tens bonds, with the use of a 10 frame to represent 100 proving to be a particularly useful tool.

Students are presented with a variety of tasks to reinforce their understanding of number bonds. They are asked to match ten frames to calculations, both in digits and words, and to fill in missing numbers to complete number bonds to 100. Differentiated sheets challenge students at varying levels, with some featuring simple consecutive colouring on ten frames, while others offer more complex shading, including halves. The reasoning and problem-solving section of the worksheet prompts students to explore the number of bonds for different multiples of 10 and to predict patterns based on their findings. Answers are provided to guide both students and teachers through the learning process. The exercises not only help students practice their arithmetic but also encourage them to observe patterns and develop problem-solving skills.
