I am about to start my 2nd long term leave in 1st grade in a few weeks. When I did a leave in 5th grade they had a daily math challenge in which they glued into their notebook and solved and then went over at the end of the day. I was in B&N the other day and saw almost the same thing but for 1st grade. Would this be too difficult for them to follow? Glueing it, solving it, etc? It is simple addition, subtraction, problem solving skills.
