Gray is for grown-ups. This duct tape is made for the young at heart. You’ll get (30) feet of 1-7/8” wide duct tape on a 3” core. You pick: aqua, chain-link fence/skyline, yellow, pink cupcake, translucent white or olive drab.

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.

You can write on duct tape, but try to change your mind later and see what happens. We recommend these 12-foot x 1-7/8” wide rolls of dark gray chalkboard tape, which you can write on with, you guessed it, chalk; or the 12-foot rolls of the more modern dry-erase tape, which we’ll pick for you in either white or day-glo orange.

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.

Why do your feet look like they are attached at a different angle when you're standing in water at the beach? Teach the children with this plastic water prism. Also make rainbows. Measures 8-1/4" x 2" x 1" with 3/8" squares across the surface to measure refraction.

These (2) reproduction maps are printed on "antiqued vellum" and are both approx 15-3/4" x 14". They show, respectively, the locations of Civil War battles and the principal events in the Revolutionary War, along with chronologies at the bottom. Lots of info packed into a small space, but the kids will read them easily. You might want some glasses. Includes both maps.

This piratical treasure trove is printed on genuine pretend parchment (from a process that involves skinning ersatz sheep). The 15-3/4" x 13-3/4" Treasure Map shows (56) actual lost treasure sites from Newfoundland to Bermuda. Call us when you finish looking. The 11" x 14" Pirates Creed of Ethics (the apostrophe was sunk along with the treasures), is a faux vellum document with a putatively real pirates' code from 1640 with (14) principles, many of which involve getting one's head split for infractions. Both profusely illustrated.

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.

The kind you hang in the front of the laboratory or on the classroom wall, which is what we suggest you do with this one. Measures 38" x 50" and is laminated to protect it from flying students. Has an aluminum frame and hang tabs on the back side. Brand new! Great quality. Please note: This item is not available for expedited shipping.

Professor! Professor! A picture’s worth a thousand lectures! Post these funky, full-color cartoon posters in the lab or classroom. The 17” x 11” posters repeat all the things you’ve been telling the students, but — let’s face it, Prof — the posters are way funnier than you are. Our each is a set of multiple posters — (6) different in the set reinforcing scientific methods. Funny for middle school through med school, student lab through working lab.

We've got (2) great grid-posters for the classroom or the lab. The 18" x 24" posters have 1/2" squares, 33 x 27, with headers on the x and y axis. The all-around borders have outer-space images or dinosaurs. Why not get both?

Dominoes aren't just for those old guys with cigars in the park. These use Cuisenaire rods to help teach basic math concepts. You get (5) tiles, 1-5/8" x 2-1/4", for numbers 1 to 10 plus (10) transitional tiles that can be used with either set (1 to 5 or 6 to 10). Includes game rules and teacher's notes.

…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.
