# Lessons I Dig

This is a list of lessons I really like. I did my best to sort and cite them. Sources are in the footnotes. Some lessons appear in multiple locations.

#### Data and Statistics

Sampling Tree Types[1]Source: Mars via Geoff Krall - Students look at a randomized array of trees with gaps and come up with a strategy to estimate how many of the trees are young versus old. Grade: 5+ Status: Haven't tried yet

#### Geometry and Measurement

Paddy Paper Shapes with Specific Areas[2]Source: Fawn Nguyen - Given a piece of paddy paper, fold specific shapes with specific areas. For example, fold a square that is 1/2 the area of the paddy paper. Grade: 5+ Status: Haven't tried yet

#### Fractions

Put In Order[4]Source: Me! via Marilyn Burns Book - Have students draw a random card with a fraction on it. Have them place it on the board/clothesline/whatever and justify why it is greater than the numbers to the left and less than the numbers to the right. Differentiate by choosing the order of students; later is harder. Later on, have students work in teams to order challenging sets of numbers. Grade: 4+ Status: Used many times with 5th and 6th graders!

#### Graphing

Graphing Stories[5]Source: Created by Dan Meyer - Students watch videos and try to plot some variable's change over time. For example, they watch a young girl slide one of those big carnival slides and plot her height above the ground over time. Includes a blank graph handout. Grade: 6+ Status: Used once with 7th graders in pre-algebra
