Why it matters. Two-digit addition is where place value starts to matter: tens with tens, ones with ones. It is the last step before adding with regrouping.
Where children slip. The classic mistake is lining up numbers by the left instead of the right, or forgetting to carry when the ones add up past nine.
Try it away from the page. Use bundles of ten sticks and loose ones. Adding 27 and 15 by hand, then bundling ten loose ones into a stick, shows why we carry.
