![]() ![]() And I would have gottenĭifferent results here. Two multiples to be 16 times 6 and 16 times 3. Method is that at every step, I could have put a #Area models for division plus#This is going to be 50 plusĢ0 is 70, plus 10 is 80, plus 5 is 85, plus 1 is 86. So that's going toīe- we can just add up all of these things on Plus 20 times plus 10 times plus 5 times plus 1 time. You're left withĭoes 16 go into 1,388? Well, it goes 50 times ![]() And then when you subtractġ6 from 28, 8 minus 6 is 2. Well, how many times does 16 go into 108? And we know 16 times 5 is 80. Times does 16 go into 268? Well, let's see. Many times does 16 go into 588? How close can we get to that? And let's justĪssume that we only know this stuff rightĪgain be too big. Multiplied by 10- 5 times 10- it'll get us to 800. And once again, howĭid I know that? Well, 16 times 5, I know So what we could say is, well,ġ6 times 50 will get us to 800. Multiplying it by another 10 to get to 50- instead of theĢ because 800 is a lot closer than 320 to our 1,000 Times does it go into 1,000? Well, we know if 16 times 5 isĨ0, we know that 16 times 50 would be 800. To be 100, because 100 times 16 would be 1,600. Or another way to thinkĪbout, how many times does 16 go into 1,000? Let's just do something atĪ very rough approximation. To think about is our best guess for how many Two results in mind while we try to tackle These as random numbers that we can use to approximate. Going to get two things out of the way, justīecause it will help us. Without overestimating, without jumping too high. Guesses for how many times 16 goes into the numbers And what we're goingįor approximation, or for essentially guessing. To do is introduce another maybe a little That right over thereĭecent way of doing it. Say 10 minus 9 is 1, or you could even borrow. The 3, depending on how you think about it. But notice, we had toĭo this little side work on the side right over here Is it, maybe, seven times? And then you might do a You say, well, it'sĭefinitely not eight times. We say, how many timesĭoes 16 go into 108? And you can approximate. But I still have thisĨ right over here, so I bring that down. I had to make sure I putĪn 8 right over here. So you'll say, 16 timesĩ- 6 times 9 is 54. Times will it go into 138? And you might try 9 first. Solve a problem like this and then introduceīit more approximation. And what I want toĭo is first think about how we traditionally ![]()
