Thank you puffin, I will check it out as well. To clarify, he is working directly with the enrichment teacher (pull-out) and the enrichment teacher working with his homeroom to teacher (independent work in the classroom) to 'teach' him algebra. This is not to say they are using the algebra curriculum that is used to instruct older children at the school. We are at the IB school (Prep - Year 12), I don't know if mathematics becomes pre-algebra, algebra, etc. as time goes on... I will need to check that out.
DS loves Borenson!!! He plans to finish up part 1 today :-) Thank you, Zen.
