Students even correct their own paces as they go. There are 12 paces a year per subject. Each set includes answer keys.
Paces are full-color up through eighth grade.
We are happy to sell individual paces at discount prices. First through Third grade does not include answer keys. If answer keys are wanted, double the price. We feel it is easy to do these paces without the answer keys for the lower grades. The High School Science has been revised, is in color and is very good.
