In this game activity students practice comparing shapes and naming something that is alike or different about them.

For this game, students work in pairs drawing two cards and naming something that is ALIKE or DIFFERENT between the two cards. The pairs draw two more cards and repeat the process until there are no more cards. The game can be played whole group or as a competition.

The purpose of this task is for students to discuss and come to understand what constitute defining attributes for triangles, squares, and rectangles. Students start by looking for attributes shared by all the instances of a particular shape. Some, but not, all of these attributes will be defining attributes.

For this task students must use reasoning skills to sort shapes based on their defining attributes. Students will demonstrate understanding of the intersections of the different categories of shapes and provide examples and nonexamples when applicable.

In this task, the students are not asked to find an answer, but are asked to analyze word problems and explain their thinking. In the process, they are faced with varying ways of thinking about multiplication.

In this problem students are comparing a very small quantity with a very large quantity using the metric system. The metric system is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.

This task requires students to work with very large and small values expressed both in scientific notation and in decimal notation (standard form). In addition, students need to convert units of mass.

This problem is part of a very rich tradition of problems looking to maximize the area enclosed by a shape with fixed perimeter. Only three shapes are considered here because the problem is difficult for more irregular shapes.

This this task about mixing paint requires students to graph ratios on a coordinate plane. It is a standard language in ratio problem.

In this assessment in a one-to-one setting, a student is shown the numbers from 1Đ10, one number at a time, in random order. The teacher asks, Ňwhat number is this?"

This assessment task can be used with a single student or a small group of students. Each student needs his or her own set of numeral cards.

This assessment may be used in a small group or whole group setting, give each student a piece of paper. Students who have trouble writing certain numbers can then get targeted practice.

With this activity, students count the number of objects in preprepared bags and write the number of objects in each bag. A reproducible sheet is provided for this activity.

The purpose of this task is to provide students with a multi-step problem involving volume and to give them a chance to discuss the difference between exact calculations and their meaning in a context.
