Due To The Thickness Of The Chalk
…there may be a slight error in your calculations. That was Sister Elmer’s warning about doing blackboard geometry on the west side of Chicago in the ’60s, but that was a long time ago, and before white boards and this excellent plastic 30/60/90 triangle for classroom use. Graduated on the longer non-hypotenuse leg for 17” in 1/8” increments. Measures 17-3/8" x 10-1/8" with (4) magnets on the reverse and a removable 5” long plastic handle on the front. In yellow and black, from Helix®.

Civil War News!
Remember the Civil War? It was in all the papers. Still is, if you order this set of (3) 20-page collections of contemporary newspaper articles compiled from mostly Northeastern U.S. papers including the New York Herald, the Sun, the Philadelphia Inquirer and others, from 1861 to 1865. Printed on slightly heavier than today's standard newsprint in a broadsheet size of 22" high x 30-1/4" wide. Students will be amazed at how long tweets were 150 years ago.

National Archives Twofer
Call them the Founding Replicas and display them in the classroom, whether at home or in school. The U.S. Constitution is 18-1/2" x 12-1/2" and the Bill of Rights is 15-5/8" x 13-5/8", both on realistic "antiqued vellum." These are nice replicas, but much reduced in size, the Constitution in particular will require magnification for reading. Our each includes both documents.

Prehistoric Poster
So the poster is really brand new. The animals on it are (1) to (190) million years old, and if that doesn't qualify as pre-history, may we stumble over a glyptodon in the dark. Invicta Plastics Ltd. of Leicester, England, printed this 23" x 16-1/2" poster with a colorful diorama to promote their authentic scale models of prehistoric animals. A time line across the bottom lists dates and data for a dozen of them, from the plesiosaur to the woolly mammoth, and compares their sizes to that of a pair of five-year-old children. Post it on the fridge to spark supper discussions, or in the classroom as a source of extra-credit questions for science quizzes.
