[quote=Anonymous][quote=Anonymous][quote=Anonymous]Here is an example of a problem my second grader received:
There are 21 kids on the playground. Some more kids joined them. Now there are 40 kids on the playground. How many kids joined the group? Write an equation using ? to show the number who joined. Solve the equation.

My 1st grader was doing those problems with smaller numbers about 2 wks ago.

Now they are into decomposing numbers into tens and ones.  For example: 12-2-4=6+3+5 yes or no

So was my first grader.  But I don't see what is wrong with having a second grader doing that problem with bigger numbers.  That word problem teaches kids critical thinking skills and is pre-algebraic.  I will have no problem if next year my first grader has problems like that since I don't think she or the majority of first graders have mastered per-algebra and could use more practice.

As for the 8 x _ = 24 problem, at some point the kids need to have their facts memorized cold so if it helps with their memorization...[/quote]
