**Title:** Geometric Shadows

**Description:**
Students will identify objects as translucent, transparent, or opaque. Upon seeing the shadow of the opaque object, students will identify the geometric figure created by the shadow.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
**Standard(s): **

[MA2015] (2) 26: Partition circles and rectangles into two, three, or four equal shares; describe the shares using the words *halves, thirds, half of, a third of*, etc.; and describe the whole as two halves, three thirds, or four fourths. Recognize that equal shares of identical wholes need not have the same shape. [2-G3]

**Title:** The Horizons of Soil in My Backyard

**Description:**
Students will work in small groups to dig holes 1 meter deep. Students will work with measurements as they dig and measure. Students will observe the different types of soil and how the soil changes as they dig. Students will write and draw in their journals about the soil horizons. The need for soil as an important natural resource will be discussed. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.
**Standard(s): **

[SS2010] LWT1 (1) 9: Differentiate between natural resources and human-made products.

**Title:** The Length of My Feet

**Description:**
This lesson, one of a multi-part unit from Illuminations, focuses students attention on the attributes of length and develops their knowledge of and skill in using nonstandard units of measurement. It provides practice with and remediation of the measurable attributes of length. Several pieces of literature appropriate for use with this lesson are suggested.
**Standard(s): **

[MA2015] (2) 16: Estimate lengths using units of inches, feet, centimeters, and meters. [2-MD3]

**Subject:**Language Arts,Mathematics

**Title:** The Area of Things...

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students have opportunities to recognize and use the attributes of length and area using nonstandard units. Several pieces of literature appropriate for use with this lesson are suggested.
**Standard(s): **

[MA2015] (2) 22: Generate measurement data by measuring lengths of several objects to the nearest whole unit or by making repeated measurements of the same object. Show the measurements by making a line plot where the horizontal scale is marked off in whole-number units. [2-MD9]

**Title:** Ladybug Lengths

**Description:**
This lesson, one of a multi-part unit from Illuminations, captures students interests, provides an introduction to and practice with the measurable attributes of length, and assesses student knowledge. The experience focuses student attention on the attributes of length and gives students the opportunity to develop knowledge of and skills in using nonstandard units of measurement. Several pieces of literature appropriate for use with this lesson are suggested.
**Standard(s): **

[MA2015] (2) 15: Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen. [2-MD2]

**Title:** Using the Number Line to Compare

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students determine differences using the number line to compare lengths. Because this model is based on linear measurement, it is a distinctly different representation from the models presented in the first two lessons of this unit. At the end of this lesson, children are encouraged to predict differences and answer puzzles involving subtraction.
