The purpose of this task is to study some patterns in a small addition table. Each pattern identified persists for a larger table and if more time is available for this activity students should be encouraged to explore these patterns in larger tables.

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

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.

This activity is designed to determine the appropriate instructional level for a student in a one-on-one interaction with the teacher.

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.

The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.

In this card game students play in pairs to practice recognizing the biggest number.

The purpose of this task is for students to find different pairs of numbers that sum to 4.

The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation.

This instructional task requires students to figure out word problems that require thinking in base 10.
