Working with numbers 11 – 19 to gain foundations for place value:
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings
Record each composition or decomposition by a drawing or equation (e.g., 18 = 10 +8); (e.g., 18-10= 8)
Understand that these numbers are composed of a base of ten ones: with either one, two, three, four, five, six, seven, eight, or nine ones added to a base of ten ones
