## Lesson 4 - Patterns in T-Charts

To encourage students to have fun on the Web while learning about Patterns
in T-Charts, here are some games and interactive activities they can
do on their own or in pairs.

**Goal **

Use a T-chart to represent and extend growing
patterns.

**Builds Upon **

Student Book pages 12-13

**Instructions for Use **

Function
Machine allows students to fill in the remaining numbers on a chart,
once the function machine has spit out its number pattern.

Introduce the idea of using negative integers
in number patterns.

To use Function Machine, drag and drop the four blue numbers, one-at-a-time,
into the function machine. The function machine automatically spits
out a number pattern into a chart. Students then fill in the blanks,
and hits "Enter" to solve the rest of the pattern.
