Chocomatic Gizmo – multiplication as a rectangular array, in the context of building chocolate bars.
No Alien Left Behind Gizmo – division and remainders in the context of putting classes of aliens on school buses.

Fractions
Modeling Fractions Gizmo – fractions strips used to explore the meaning of numerator and denominator
Equivalent Fractions Gizmo – compare fractions using a fraction-tile-making machine
Fraction Artist 1 Gizmo – create modern “paintings” in the style of Piet Mondrian, and describe them with fractions. (There are actually 2 Fraction Artist Gizmos. The lesson in the second one is slightly more advanced than in the first.)

Fractions, decimals, and percents
Modeling Decimals Gizmo – model and compare decimals with area (grid) models.
Fraction, Decimal, Percent Gizmo – compare fractions, decimals, and percents with area (grid) models.
