This google slide show will be used by third grade teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Students then engage in discourse to tell whether they believe the math presented is a fact (true) or a fib (false) and why.

This google slide show will be used by third grade teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Students then engage in discourse to tell how the two pictures, numbers, expressions, or equations are the same and how they are different.

This google slide show will be used by third grade teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Students then use algebraic reasoning to discuss what each shape in the mobile is "worth".

This google slide show will be used by third grade teachers with their students as a numeracy routine. Students should be given time to notice and wonder about each slide. Students then engage in discourse to find which two statements are mathematically correct and which one is not.

The images on this google slide show are best used in the context of a number talk where children are gathered in a common space and know the routine of sharing thoughts and ideas. Teachers use talk moves to keep the dialogue going among and between student, focusing on mathematical ideas and vocabulary found within the images. The teacher’s role is to facilitate the conversation, allowing a forum for the sharing of important ideas.

This google slide show organizes "Who Am I?" number puzzles in a sequence by weeks. Puzzles are online and linked to this slide show. Teachers can use these with students to promote number sense and precise mathematical vocabulary.

This google slide show organizes "Would You Rather?" questions in a sequence by weeks. This series is recommended for third graders in the third quarter. Teachers can use these with students to promote number sense and precise mathematical vocabulary. Students will construct viable arguments and discuss their choices mathematically.

In Module 3, students' understanding of addition and subtraction of fractions extends from earlier work with fraction equivalence and decimals. This module marks a significant shift away from the elementary grades' centrality of base ten units to the study and use of the full set of fractional units from Grade 5 forward, especially as applied to algebra.

In this recycling activity students conduct a poll and display data showing which type of material the survey population feels is the best for shopping bags. Students share their results in a data display of their choice and then use the data to draw conclusions and create a recycling plan. The activity includes the student worksheet, extension suggestions, and related resources.

This lesson unit is intended to help you assess how students reason about geometry and, in particular, how well they are able to: use facts about the angle sum and exterior angles of triangles to calculate missing angles; apply angle theorems to parallel lines cut by a transversal; interpret geometrical diagrams using mathematical properties to identify similarity of triangles.

This lesson unit is intended to help teachers assess how well students are able to use geometric properties to solve problems. In particular, it will help you identify and help students who have difficulty: decomposing complex shapes into simpler ones in order to solve a problem; bringing together several geometric concepts to solve a problem; and finding the relationship between radii of inscribed and circumscribed circles of right triangles.

The applets in this Interactive Geometry Dictionary (IGD) will allow students an opportunity to explore finding the area of some common shapes. The applets demonstrate how to find the area of a triangle using the area of a parallelogram, which in turn can be found using the area of a rectangle. This tool also supports the lesson "What's My Area" cataloged separately.

This lesson unit is intended to help teachers assess how well students are able to: interpret data and evaluate statistical summaries; and critique someone elseŐs interpretations of data and evaluations of statistical summaries. The lesson also introduces students to the dangers of misapplying simple statistics in real-world contexts, and illustrates some of the common abuses of statistics and charts found in the media.

This project is useful for math classes that have an opportunity to allow students to explore deeper into math related careers.

This Java interactive tool can be used to create dynamic drawings on an isometric dot grid, and to explore volume, surface area, and congruence concepts. Users can draw figures using edges, faces, or cubes and can shift, rotate, color, decompose, and view figures in 2‑D or 3‑D with this applet. Instructions on using and exploring with the tool are included on the page. A related multi-lesson unit from Illuminations for middle school students is linked to the side.

This lesson plan combines physical activity (jumping jacks) with data collection. The purpose of this activity is to compare and contrast the use of mean, median, and mode as the best measure of central tendency. The lesson plan includes three worksheets, extension questions, and assessment options.

This google slide presentation describes a numeracy routine for kindergarten use during the third quarter. The routine involves sequencing various representations of numbers on a clothesline. Printable materials are included.
