Teacher professional development and classroom resources across the curriculum

## Comparing Representations

Statistical analysis allows us to organize data in different ways to draw out potential patterns in the variation. Review and compare data represented in a bar graph and accompanying tables depicting relative and cumulative frequency.

## Comparing Slopes

Control the slope of lines passing through the origin (0, 0). Keep track of what changes when the slope becomes positive or negative, and when slope is larger or smaller than 1.

## Connecting Themes and Disciplines

Connect themes and content to teaching strategies and activities. Practice developing lesson ideas by listing new concepts you would teach and activities you would use to teach them.

## Constant Area

Do figures with the same area have the same perimeter? Arrange and rearrange 12 square tiles on a grid, and then measure the perimeter of each shape you create.

Use a "linkage strip" to to build quadrilaterals with different sets of lengths. Once you build a quadrilateral, see if you can deform it into a different quadrilateral with the same side lengths.

## Constructing Triangles

Use a "linkage strip" to build triangles with different side lengths. When you build a triangle, see if you can deform it into a different triangle while keeping the side lengths the same.

## Counting Raisins

Count the number of raisins in seventeen half-ounce boxes of raisins. Then come up with a solution to determine how many raisins are in Brand X's or Brand Y's box of raisins.

## Counting Stairs

Build staircases out of square blocks. Look for patterns and come up with a rule or formula to predict the number of blocks in any staircase.

## Creating a Line Plot

Watch as a physical stack of coins is added as a series of dots to a line plot.

## Cylinders, Cones, and Spheres

Is there a relationship between the volume of a sphere and the volume of a cylinder of equal diameter and height? What about the volume of the sphere and the cone?

## Dealing with Data

Using three sets of data from a second grade class, think of an aspect of the data you would like to focus on and then choose the type of graph (line plot, stem and leaf plot or histogram) that best represents that aspect.

## Determine Conferencing Practices

Organize and navigate a challenging parent-teacher conference. Decide which factors contribute to a successful conference, and which factors influence a difficult one.

## Determining Rotation Symmetry

Explore properties of rotation symmetry. Determine the angle of rotation for different images.

## Difference Trains

Build your own difference train with one, two or three difference between blocks. Think about your reasoning as you work.

## Differentiate Instruction in a Class

Group children with varying literacy abilities and choose the best instruction to address their literacy needs.

## The Distance Formula

Plot points on a graph. Use the Pythagorean theorem to calculate the distance between them.

## Division with Manipulatives

Area models offer a visual representation of mathematical operations. Use these models to perform multi-digit division.

## Drawing a Box Plot

Learn how to represent the Five-Number Summary graphically using a box plot.

## Elements of a Story

Explore different ingredients, or elements, that go into stories and make them so much fun. Read the story, "Cinderella," and look at all the different pieces of the tale to see how they all fit together.

## Elements of Authentic Instruction

Analyze three classroom segments and identify teaching strategies that illustrate authentic instruction. Give examples to support your answer and compare your answers to those of other teachers.
