DEVELOPING UNDERSTANDING OF ADDITION AND SUBTRACTION add and subtract one-digit and 9-4=5 numbers to 20, Year 1 14 + 5 = 19 including zero Objectives 19 - 14 = 5, etc read, and interpret mathematical statements Work with all numbers up to 20. involving addition (+), Recall of Facts subtraction (-) and equals (=) = + signs Mental Jottings with representations represent and use number Immerse children in practical opportunities to develop understanding of addition If we know 4 + 5 = 9 and related subtraction and subtraction. Link practical representations on a number track on a beadstring We also know: , facts within 20 to recording on a number line. By the end of Year 1 children should be able to 5+4=9 recall and use facts within and to 20. Children need to be secure with Using and Applying these skills in unfamiliar contexts before moving into the Year 2 objectives. 4
