10 activities that allow you to measure angles.

This is a PDF game that can be printed and played.

### Crickweb

Great site for practice.

### Harcourt Brace

This site is a glossary with visual examples of most math vocabulary. There are good examples of pictographs, bar and line graphs, line plots,stem-and-leaf plots, and frequency tables that you can use for questioning and discussion. All have intervals greater than 1. Check grades 3-5 for different data on the graphs.

### Harcourt

This site requires kids to classify polygons by the number of sides.

### Eduplace

This is a good blackline for concentration cards for lines, line segments, parallel, and perpendicular lines.

### PBS

THis is a GREAT introduction to line plots. You'll need to click on the menu button at the top left, and then the Bianca Video button at the bottom of the list.

This is a great site for exploration, especially when introducing 3D shapes. You'll need to talk with students about how in the UK they call rectangular prisms cuboids though.

### Harcourt

This site sets the beginning and end time, and you must decide how much time has elapsed.

### Mister Teacher

This is an awesome lesson for teaching transformations. I recommend giving each child two die cut shapes with the top, buttom, left, and right sides all being different. (Two identical mittens or profile view of animals work wonderfully.) They can use these as you go through the lesson. Be sure to print the supplements to use with the lesson.

### Interactive Stuff

This is a great site for allowing kids to model and count cubic units to find volume. If your time is short, you may want to click ahead and find the prisms with smaller volumes to build.

This is a great site for review of names of 3D figures. Since it's interactive, the kids can manipulate the shapes on the SMART Board. You'll need to talk with them about the fact that in the UK they call rectangular prisms cuboids though.

### Crickweb

Polygon Sort is a good link for teaching regular and irregular polygons. It's not self checking for individual student work, but it does allow printing so that you can review work later.

### NCTM

This is a great visual to use for demonstrating transformations.

### Maths Net

This is a great interactive site that allows students to add cubes, rows, and then layers to a box with given dimensions, then click on the sides to close. It's a great way to get kids to understand conceptually why width X depth X height works. Use it to display what kids are doing with blocks at their desk.

### WorksheetWorks

A great site for creating worksheets and capturing images for your SB notebooks.

### Crickweb

Use your knowledge of benchmark angles to estimate the measure of angles. (45, 90, 120, and 180 degrees.

### Math Frog

Click Welcome, 4th grade, then scroll down to Dividerama. This site is great for step by step long division practice. There's also a printable worksheet for more practice. For more challenging problems, try the Grade 5 version.

### Eduplace

This is a great blackline for use with quadrant grid battleship games. To meet this SLE, kids need to be comfortable with the terms horizontal/x-axis, vertical/y-axis, and ordered pairs.

### Nrich

This would be a great activity to use with your SB floating pen tools. Though the focus is multiples, it could lead to divisibility by 2 and 5, and I'm betting you could work 10 in there too.

### Crickweb

This would be good for a whole class or small group lesson. It can be used to discuss shape names and properties if it's guided.

### NLVM

This site allows you to hold the shift key and click on sides, vertices, and edges. As you select each, the computer will record the count. Click new shape for practice with other solids.

This game is fun, but you'll have to use a calculator to divide the numerator by the denominator to find the decimal.
