### Year 1

Add with numbers up to 20.

Use numbered number lines to add, by counting on in ones. Encourage children to start with the larger number and count on. Children should:

• Have access to a wide range of counting equipment, everyday objects, number tracks and number lines, and be shown numbers in different contexts.
• Read and write the addition (+) and equals (=) signs within number sentences.
• Interpret addition number sentences and solve missing box problems, using concrete objects and number line addition to solve them:
8 + 3 =  | 15 + 4 =  | 5 + 3 + 1 =  |  +  = 6

This builds on from prior learning of adding by combining two sets of objects into one group (5 cubes and 3 cubes) in Early Years.

Key vocabulary: add, more, plus, and, make, altogether, total, equal to, equals, double, most, count on, number line
