Array Builder Build the array with your hands — see why groups × in-each makes the total. Fair Share Deal a pile fairly into equal groups — the hands-on way to see division, quotient and leftover. Slice’s Pizza Argument Slice says an eighth beats a fourth. Decide who gets more pizza, then cut real paper to settle it. How Many Groups? Make groups of a set size from a pile — the OTHER kind of division: you know how many in each, so how many groups fit? Break It Apart Split a hard times fact into two easy ones — see why the total stays the same. Predict the Product Guess how many in all first — then build the array to check. Why we multiply, not add. Fractions on the Line Guess where a fraction lands, then see the steps — predict, look, and find out why. Fade-Out Chant Learn a tricky times fact by heart — say it, then say it back as more and more words fade away. Send-offs Six fifties on the :55 — predict each leave time and watch the clock draw a shape. Count the Moves A form done on both sides doubles the count — then count to ten in Korean or Japanese. Pass It On Everyone who just heard tells two more: 1, 2, 4, 8 — which day has the whole school heard?
