This fantastic resource for interactive whiteboard tools has been circulating on Twitter. The site provides excellent manipulatives, gameboards, workmats and storyboards for K-4 classrooms. It takes time to discover all of the hidden gems, so I’ve highlighted an activity below that you won’t want to miss!
Choose the Place Values Millions Workmat and Number Cubes Manipulatives
Game #1: Place seven number cubes on the screen. Choose Roll All Cubes. (Note: The number 10 is on one face of the cube, so some cubes many need to be re-rolled individually by selecting the cube and clicking on the icon in the upper right corner.) Challenge your students to place the number cubes on the workmat to create the largest number possible or the smallest number possible. Ask your students to think about place values by creating a number between two specific guide post numbers such as three million five hundred thousand and four million.
Game #2: Place seven number cubes on the workmat. Choose Roll All Cubes. Have your students build a number that you describe using the cubes. Ask them to place one cube at a time on the workmat to create a number according to your directions. For example: Put the six in the tens place. Put the five in the hundred thousands place. Put the one in the hundreds place. etc.
Game #3: Place one number cube on the screen. Roll the number cube. Tell your students that their challenge is to create the largest number possible (or the smallest number possible) by placing the numbers you roll in specific place values on the work mat. However, the students will only see one number at a time, and they will have to place that number on the mat before they will be allowed to see the next number. Once a number is placed, it can not be removed. Vary the game by rolling two or three number cubes at the same time and having your students place several numbers at once.
All of the above games can be modified for different levels by using fewer number cubes, by using more number cubes or by choosing the Place Values Billions workmat.
As with all interactive whiteboard activities, be sure to encourage all students to answer by using paper and pencil or individual whiteboards as described here.

These sites focus on two angles concepts: Estimating the size of an angle when given its measurement and estimating the measurement of an angle when shown its size.
1. Begin by selecting Show the Angle. Use this application to explore the relative size of angles and to work together to establish “benchmark” angles to guide the estimation process. For example: Is the angle less than 90 degrees? Is the angle between 90 degrees and 180 degrees? Help your students to develop the concept of the size of ten degree increments.
2. Click Teacher Controls. Choose Make the Angle Game. Use this application to practice creating an angle to match the given measurement. Use a think aloud for the first problem. Answer the problem while explaining the reasoning behind your answer. For the next few questions, have students draw their angle estimations independently or in small groups. Then have them share the strategies they used to determine their estimations. Finally, choose one student to answer for the class. (You may want to skip the think aloud if you want students to come up with their own estimation strategies and not be influenced by your demonstration. Be sure to share and discuss the strategies as a whole class.)
3. Click Teacher Controls. Choose Estimating up to 90 or Estimating up to 180. Have the students estimate the angle measurement of the given angle individually or in groups. Have them explain their thought process. Then choose one student to answer for the class.
4. Click Teacher Controls. Choose Make and Measure. This could be used for a partner activity at a center or as a whole class activity by dividing the class into two different teams. Have the first team create an angle and measure it with the protractor while the second team is not watching. Then, have the second team guess the angle measurement and then measure the angle to check their accuracy. A few suggestions for game rules: The angles created must end in 5 or 0. Rarely will the students guess the measurement with 100% accuracy so a point system that allows for close answers works well. 3 points for 100% accuracy. 2 points if the estimation is within 5 degrees. 1 point if the estimation is within ten degrees.
The last two websites can be used as whole class practice, by groups during center time, or by individual students on computers at school and at home. The second website asks students to set the angle of a laser beam to destroy an alien spacecraft. It is a nice introductory activity since the angle measurements are in 10 degree increments. The third website asks students to help the monkey find the banana by creating an angle with the given measurement. This site is more challenging since all 360 degrees are used.
Introduce students to non-standard measuring tools with this online video. After the first student on the video has measured the given distance in footsteps, pause the video and ask your students what result they would expect if another student were to measure the same distance in footsteps. What would happen to the measurement if the second student’s foot size was larger? What would happen if their foot size was smaller?

Whole Class Activities: Add variety and a new challenge to basic multiplication facts practice by asking your students to find missing factors in multiplication problems. Use the first three websites to demonstrate finding missing factors and for whole class practice with the skill.
With the appearance of quality online virtual manipulatives, many traditionally paper and pencil activities have become opportunities to engage students with technology, as is the case with the following website.
Classroom Integration Ideas:
Students can create a printable flip book to demonstrate their understanding of multiple concepts. Here are a few examples:
Cause and Effect
Direct your students to create a flip book with alternating pages of causes and effects. Have them share their books with each other and turn the sharing into a prediction exercise. Have the student being presented to brainstorm potential effects from each cause in their partner’s book before flipping the page to see their partner’s chosen effect.
