I originally produced this resource to help my own children learn to tell the time. It has since been used extensively to support teaching time telling to children aged between 5 and 10 years of age.<br />
<br />
This Math resource provides clear visuals and activities to support children in the development of time telling skills. The aim is to encourage children to take a hands on approach and enjoy learning to tell the time.<br />
<br />
Slides are provided in three different formats; full colour, black and white photocopiable and tinted dyslexia friendly.<br />

Beginning with a quick refresher of the definition of closure, this advanced (extra credit?) worksheet asks students, "In which of these 20 examples of a set and an operation is the set closed under the operation?"<br />
<br />
Examples include: "Composite numbers under multiplication?", "Even numbers under addition", "Square numbers under addition."<br />
<br />
I hope it challenges most of if not all of your brightest students!<br />

Easy print-and-cut-out resources. Recommend that you use card-stock. See attached directions for a example problem that it can be used for. Cut out the triangles at the bottom of the page first!<br />
<br />
This is a great resource for when you first introduce the unit circle and sign and cosine. By cutting out the triangles and placing them appropriately on the unit circle students can "see" the values trigonometric (trig) functions of common values such as 30 degrees, pi/4, etc. Students get very engaged using this tool, and really "internalize" rather than just "memorize" these important facts and concepts.<br />
