Beware: Invisible Ink


This week Kal-El has been working through the first presentation of the multiplication bingo board.  The first time you work through the board you draw loose equations.  The second time you draw a single product and find an equation on the board that satisfies that product.  The third time you place all tiles of a particular product thereby finding all equations that satisfy that product.


Do those tiles look blank to you?  I tell you, this work would be a lot easier if we could easily read the product tiles.  Seriously, I don't think that the color coding is so important that they needed to use yellow ink.  The brighter the light in the room, the harder it is to read the tiles. We have to draw the blinds when he works on the board.


Here's a close-up just in case you thought distance might be the problem.  As always, you can click on the photo to see a bigger picture.

  1. If manufacturers would ask me about this material (they don't ;) ), I would say "yellow tiles with black ink". Best of both worlds (color-coordinated and readable).

  3. Wow that is terrible! I think it has more to do with the shades of ink and wood they use. We have tiles from Nienhuis and Boston, both of which are very easy to read. The Nienhuis ones are super light wood and dark yellow ink which is perfect, the set from Boston has more of a wood grain pine shade but has dark yellow ink so it still shows up nicely. Looks like the company you purchased from used a light yellow ink on a darker slightly colored wood. I'm not sure where you purchased them from but I assume its a discount supplier, they tend to not notice the little details like this. We were lucky enough to get ours as part of a lot of used materials, otherwise I would have been ordering from the discount suppliers as well. It is so hard to know what materials will be like when ordering online.
