Helix Magnetic Whiteboard Geometry Set – 4 Piece Teaching Kit for Classroom – Large Magnetic Math Tools for Whiteboards & Blackboards – Durable, Easy to Store | Large Math Tools - Classroom Teaching Kit - Durable - Easy to Store - for Blackboards - Educator Supplies

I was looking for large tools to teach my homeschooler geometry. This kit has been amazing! I definitely recommend it.

I’m glad I got them, but be warned that the compass is very hard to use! I’ve spent hours practicing and I’ve gotten better, but it’s still very hard to get right and to perform constructions with. However, I’m sure they’re all hard to use and when it does work out it’s a great teaching tool since I can’t go to every students desk to do the constructions with a tiny compass. The triangles and protractor are great and I use the ruler constantly for all sorts of purposes! The magnets could be stronger though and I find that they slide quite a bit.

Large and visible. Great for work on the white board

Excelente inversión. Aunque si pensé sería un poco más grande.

Nice set, but DOES NOT WORK WITH GLASS WHITE BOARDS. If the magnetic part of this set is what you are looking for, only buy it if you are using a standard magnetic white board (not the glass kind). Otherwise, the set and carrying case are very nice!

I bought this for my son who uses a large whiteboard for math stuff that involves graphs, straight lines, triangles, circles, etc. The pieces are all bright yellow and have bold markings for measurements, I'm sure these are intended for classroom demonstration. The tools are very magnetic and stick well, they don't move when you're drawing against them but the handles make it easy to pull them off and reposition. The compass however is almost comical with huge 18" arms, it'll take some practice to tame.

With the exception of the compass, this set is very useful. The magnets work great and they are durable. I’m glad I purchased the set. I will say I wish the compass was replaced by a protractor shaped piece to draw a standard semi-circle or doubled up to make a circle. That would be easier than trying to manhandle the compass and negotiate a marker at the same time. I gave up on the compass and stored it away. The other items stay in my desk drawer right next to the white board. I use them often.

I don’t use the compass. The compass is too flimsy for what I’m doing. The rest of the other tools work great. The magnets in the straight edge aren’t strong enough to keep it on the white board but the rest of the tools have no issue.

Toll

The magnets just aren't quite strong enough to hold them up where you put them, had to buy extra magnetic tape and cover the whole backing so they wouldn't slide down the board, also a bit flimsy/thin plastic, overall not really worth the price, if it was cheaper to reflect the actual materials used then fine but as it is not great quality

Me gusto el diseño de las reglas.No me gustó el espacio de la caja tan justo.Sugiero que para poder guardar el juego de reglas con mayor facilidad la caja sea más alta.

Vraiment top ! Super pratique

Le compas bouge pendant le traçage (instable).La règle et l'équerre ne s'ajuste pas correctement.
