Comparing Growth, Variation 2
A twist on the first variation of the growth task, this task poses an argument on two explanations of which snake grew more, based on the idea that two is a larger part of six rather than 10.

Three of a Kind
One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

Which is Bigger?
To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.

Here is an engaging instructional activity which invites learners to cut a strip of adding machine tape that is their height. They decorate their strip, arrange the strips from shortest to longest, and then discuss predictions.
Kids Learning Station
Long and Short
Youngsters examine four sets of familiar images, circling the one that is short and underlining the one that is long. This is likely best done 1:1 with kids or as a big class, projecting the image for everyone to see.

Measure the Length in Meters
Which is longer? Learners explore measurement through 10 object comparisons. They measure each object against a row of squares, each square representing one meter. Although the directions simply ask which item is larger, encourage kids...
