For this interactive, students place numbers on the correct spot of the 100 chart. There are two levels of difficulty. Beginner-students are given one line of the 100 chart with two missing numbers at a time & advanced-students are shown the entire 100 chart with twenty missing numbers. Students receive a funny surprise at the end of the activity.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials Set of cards from 1-100, these can be purchased or created using a black marker and index cards Setup Sort the 1-100 cards into sequential gr...

An interactive applet and associated web page that demonstrate the the concept of adjacent arcs. The user can 3 drag points around a circle that define the endpoints of two adjacent arcs. Web page has the properties of adjacent arcs. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This assessment is a continuation of the Changing Numbers activity, using the numbers 11-20.

Teachers (and then students) lead the class in chanting numbers from 1 to 120.

In this activity, students work with a partner to identify numbers on a grid.

Students practice counting sequences by standing in a circle and counting one by one.

In this interactive, students various items to count. After counting the items, students type the correct number in the box provided.

Students practice crossing from one family to the next in counting forward with this concentration game.

This activity is a version of the traditional memory or concentration game. Students play with a partner to find a matching pair for the card they turn over. (Ex. “I have 29, I need 30.”)

In this assessment task students will complete a hundreds chart that already has numbers filled in. They will write numbers to complete a 50 or 120 grid task sheet. This is a small group or whole group. A 50 and 120 grid assessment task sheet and a rubric are provided.

This is an independent assessment to assess students' ability to write missing numerals on the hundred chart.

In this activity, partners play a game to see who can fill in the 100 grid first.

In this assessment task students will work with partners to fill out a 100 chart. A die is rolled. The number rolled becomes the number of numerals students will write.

For this interactive activity, students place numbers on the correct spot of the 100 chart fragment. This is an interactive  Google Slide activity.
