poetic license Posted May 24, 2012 Share Posted May 24, 2012 We had a neat moment today and since I'll look funny sharing it on facebook, I'll just share here ;) I was talking about place value with DS 5 and how we can understand numbers like 512 in terms of tens and ones instead of hundreds, tens, and ones. So it would be 51 tens and 2 ones. Later on, we were doing a little expanded notation, so I showed him how: 512 = 500 + 10 + 2. He then excitedly exclaimed, "Yeah, but we can also say... 512 = (50 X 10) + 10 + 2 Or-- 512 = (51 X 10) + 2." I felt like doing a happy dance to see all this "click" in his head, and when I told my husband, he half jokingly claimed that I was making all this up. :tongue_smilie: This is so exciting for me because I feel like I am relearning math all over, except this time with some real love and excitement for it. :D Quote Link to comment Share on other sites More sharing options...
