## Ten Frame

Pre-K-2

Math Content:
Number and Operations

Thinking about numbers using frames of 10 can be a helpful way to learn basic number facts. The four games that can be played with this applet help to develop counting and addition skills. (This applet works well when used in conjunction with the Five Frame applet.)

This interactive is optimized for your desktop and tablet.

A video tutorial is also available to demonstrate how to use this applet.

### Modes

• How Many: Identify how many items or empty squares there are.
• Build: Drag a certain number of items to the frame.
• Fill: Determine how many items are needed to fill the remaining squares.

Choosing Play All from the Games menu will randomize which of the four games is played.

### Options

The items to be used can be chosen in the upper left corner: circles, bugs, stars, or apples.

### How to Use

• The Next button advances to the next problem.
• The Done button should be clicked when a student believes that she has correctly completed a frame.
• The number buttons at the bottom of the screen can be used to enter an answer, or the computer keyboard can be used.

Questions for Students

1. What does the word "zero" mean? Where is it on the number line?
2. Split 10 apples into two groups. Can you do it a different way? Can you split it into three groups?
3. Can you count to 10? Can you count down from 10?
4. Create a story problem using one problem in the interactive.
