[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]What is practical math?[/quote] Faster. Can be done in your head for the most part. My new math kids cannot add 44 + 27 in their heads at all. They have to write it out and do the boxes or pyramids. 44 + 27 = 40+4 and 20+7 40+20=60 4+7=11 60 +[u]11[/u] 71[/quote] I just asked my rising 6th grader to solve this in her head. She said she added 44 + 20 and then the 7. I, an old math person, mentally added the 7 and 4 in the ones column and carried the 1. Not sure mine was more efficient. [/quote] How your rising 6th grader solved is old mental math, that's how we learnt it in the 80s. Mental math old or new involves breaking the second addend to simple numbers, in this case, 27 is split into 20 and 7, before being added to 44. You may call yourself old math person, but you picked up an inefficient technique. [/quote]
