How RightStart Math teaches mental math

RightStart Math makes mental math the centerpiece of arithmetic instruction, using the AL Abacus to train children to visualize numbers as groupings of five and ten that can be mentally manipulated. Before any pencil-and-paper algorithm is introduced, children learn to see 8 + 7 as 'eight is three-away-from-ten; take three from seven, make ten, have four left: 14'—a visualization they've rehearsed on the physical beads. Math games reinforce this visual arithmetic daily in a playful context. These free printable mental-math worksheets guide children through the same grouping strategies in written form, presenting problems that reward the ten-visualization approach rather than counting-up or rote recall. Children who internalize this work carry a mental abacus they can use for the rest of their arithmetic lives.
