Texas Instruments: Estimation and Precise Measurement

Students use the calculator to compute products of numbers and to find answers to division problems. The activity is designed to help students develop number sense with the operations of multiplication and division.

Students learn the conversion relationship between inches and centimeters through data collection. The data collected results from measuring items using inches and centimeters as the units. They use a TI-73 to input the data into lists...

This App contains five games that reinforce skills from the number and operations, geometry, and measurement standards. These games help students build skills in ordering numbers, choosing equivalent fractions, estimating and drawing...

In this activity, students develop estimation and mental arithmetic skills for integer addition and subtraction. In this activity, the Number Line application will be used for targeting estimations.

In this activity students learn to use estimation to determine the number of candies in various size cylinders. They compare estimated numbers to actual numbers and investigate the relationship between the two numbers.

This activity will introduce and/or reinforce estimating the measurements of angles.

In this activity students explore the use of manipulatives to conduct simple geometry and measurement activities.

This activity introduces students to the importance of benchmarks when estimating measurements.

In this activity, students will collect data by measuring different linear objects and develop a strategy to determine the conversion factors required to convert from one linear measurement to another.

In this activity, students will reduce a cafeteria recipe to suit a household recipe. They use compatible numbers to choose smaller measurements while retaining the original proportions.
