In the Range
Students will interpret the rounding involved in measuring to identify the possible range of a given measurement.https://education.ti.com/en/activity/detail/in-the-range
Helping Hands
Students make their own finger signs for the numbers from zero to ten. Students relate each finger sign to its number name and numeral. They use the numeral keys and scrolling feature of the TI-10 to enhance the concrete-symbol connection and sequencing of numbers.https://education.ti.com/en/activity/detail/helping-hands
Fraction Forms
Students will compare the results of using division to create fractions under the different mode settings for fraction display and make generalizations from the patterns they observe.https://education.ti.com/en/activity/detail/fraction-forms
Food for Thought
Students learn to count in tens up to 100. They also learn to build 2-digit numbers.https://education.ti.com/en/activity/detail/food-for-thought
Double Your Design
Students learn to use pattern blocks to investigate symmetry by building a design, making its mirror image, and using the calculator to determine the value of both the design made and its reflection.https://education.ti.com/en/activity/detail/double-your-design
Yards of Tin
Students solve a problem involving surface area of cylinders. They find the surface area and the amount of tin needed to make the cylindrical parts of ten long open pipes.https://education.ti.com/en/activity/detail/yards-of-tin
NUMB3RS - Season 3 - "Killer Chat" - The Perfect House
The FBI found three bodies in different unoccupied houses, all for sale. Because the victims are completely unrelated, Charlie decides that profiling the houses might reveal a distinct pattern to find out where the killer will strike next. By using a Multi-Attribute Compositional Model, the house...https://education.ti.com/en/activity/detail/numb3rs--season-3--killer-chat--the-perfect-house
Recurring Remainders
Students will use the calculator to investigate the patterns formed by remainders in whole-number division.https://education.ti.com/en/activity/detail/recurring-remainders
Number and Operation Sense: Whole Numbers
Students attain a basic understanding of numbers and number operations, developing number sense, and gaining fluency in arithmetic computation. They also learn to use the calculator to explore the mathematical principles behind the standard multiplication algorithm for multidigit numbers.https://education.ti.com/en/activity/detail/number-and-operation-sense-whole-numbers
Names for One-Half
Students use their understanding of integers, fractions, decimals, and operations to find mathematical expressions that equal one-half.https://education.ti.com/en/activity/detail/names-for-onehalf
Transient Circuit Analysis: Numeric
Describes how the differential equation plotter is used to solve the second-order circuit presented in Chapter 2 (Topic 8) by expressing it as a system of first-order differential equations.https://education.ti.com/en/activity/detail/transient-circuit-analysis--numeric
Cereal Numbers
Students build numbers from zero to ten with cereal and connect the number name and numeral. Students also explore number sentences for numbers up to ten.https://education.ti.com/en/activity/detail/cereal-numbers
Calculator Pattern Pizzles
This lesson will allow young children to explore number patterns and relationships while introducing the calculator at the same time.https://education.ti.com/en/activity/detail/calculator-pattern-pizzles
Bats Triangular
Students use manipulatives to construct a pyramid. The manipulative pyramid then becomes the basis students use to construct a pictorial representation of a pyramid. The TI-10 is used to show symbolic representation of students actions and also aids students in viewing the developing pattern.https://education.ti.com/en/activity/detail/bats-triangular
Area Patterns
Students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They will then use the patterns and the calculator to predict the number of blocks it will take to build a specific shape in the sequence.https://education.ti.com/en/activity/detail/area-patterns
Analyzing Number Cube Sums
Students extend their understanding of theoretical probability and patterns. They use number cubes, to build awareness that a fraction and its decimal and percent representation on the calculator are "close," but not necessarily equal.https://education.ti.com/en/activity/detail/analyzing-number-cube-sums
