### SoftSchools

Be sure to set the scale for greater than one to teach this SLE.

### Worksheet Works

Note that this SLE requires students to be able to use physical models, pictures, and organized lists to find combinations of two sets of objects. While the sheets you can create at this website don't do this, they're great problems to use with this type of activity.

### Harcourt

This site gives a great visual representation with regrouping. Print the activity sheet to use with the site,and allow kids to use manipulatives also.

### NLVM

This site allows you to demo finding area including half squares. Problems are given, but you can also clear the board and make your own. Rubber bands can be used to divide the areas for color coding.

### Learning Planet

Set the counting number to practice. Kids will need to write as multiplication sentences. Note that after the first two or three games the site no longer uses multiples.

This site gives practice with join change unknown problems. It's perfect for differentiating stations because problems become more difficult as the student shows mastery.

### Crickweb

This site lacks context to meet this multiplication SLE's objectives, but it's good practice with number concepts.

### Harcourt

This site gives a great visual representation with regrouping. Print the activity sheet to use with the site,and allow kids to use manipulatives also.

### NLVM

This is a great site to use for demo while students use base ten blocks to solve problems. Set the number of columns to 3, then click create problem. You can drag blocks down to make each part of the problem, then click begin problem. As kids borrow, the computer shows the corresponding steps for the standard subtraction algorithm.

### NLVM

This is a great site to use for demo while students use base ten blocks to solve problems. Set the number of columns to 3, then click create problem. You can drag blocks down to make each part of the problem, then click begin problem. As kids trade, the computer shows the corresponding steps for the standard addition algorithm. Note that ten ones can be converted to a rod by dragging a rectangle around the ones.

### Crickweb

Flip is a great site for modeling data collection about card suites, numbers, etc. After using the site, kids can then work in groups or pairs to collect more data.
