The abstracting component of RAMR is where oral and written number names and written numerals are introduced. Start with a situation from the world, model this with sets and number lines (e.g. count objects and count along number tracks and number lines – note that the number line, or length, model requires counting jumps not starts/ends of jumps). Sequence the numbers – do 1–4 first, 0 second, 5–9 third and all 0–9 finally. Move on to using numerals in activities focusing on one more/one less, comparing and ordering, and ordinal numbers (first, second, third, etc.). Then use numerals for ten, counting on/back, composite numbers (separate subgroups) and other advanced counting ideas.
