| Even considering its purpose, don't you think it's a bit repetitive? Sure it's 14 questions on the surface, but it's basically only one question. You either get them all right, you get them all wrong, or you make a stupid mistake or get bored and careless and wind up somewhere in between. Students aren't going to learn anything new from this activity, since it's basically just asking one conceptual question and then testing their subtraction skills, which they should have mastered in 2nd grade or so. |
