This Learning Resources Teaching Cash Register is one of the most-loved toys at our house. This would be great for working on math skills at home. My youngest son got it for his birthday, but my older kids have a great time with it too. You can use the scale, scan pretend credit cards and practice your math skills when the register helps you add your money. It comes with play coins, but this register also recognizes real money. It has an automatic shut-off feature as well, so no unnecessary battery use. Learning Resources also offers a smaller Pretend and Play cash register, but I think the Teaching Cash Register is worth the extra money. The price on this register has dropped to 50% off and just $27.49 with free shipping if you choose super saver shipping. The price on this cash register is the lowest I have ever seen it right now. It’s priced at $60 at my local independent toy store. If your order totals $35 or more, it will ship for free.
