when counting by hundreds from 43 to 1043 which numbers will we say select all that apply so let's do that let's start with 43 let's start with 43 and then let's just keep adding a hundred to 43 so if we had a hundred 243 we're going to get 143 143 now let's keep adding 100 to it if we add another hundred we're now going to have to hundreds 243 or 243 now let's keep adding a hundred to it so if we add another hundred we're going to have 343 343 I think you see what's going on here you add 100 again you're going to have 443 I'm coloring in the hundredths place so that we can keep track of that you add another hundred you're going to have 543 543 then at another hundred you're going to have 643 add another hundred you're going to have 743 743 let's keep adding 100 and keep adding 100 add another hundred you're going to have 843 843 add another hundred you're going to have 943 or you could do that as 900 and 443 or 904 tens and three ones and let's add another hundred so if you add another hundred you could view this as ten hundreds and 43 10 hundreds and 43 but 10 hundreds is the same thing as 1,000 so we would read this as one thousand forty three and that's what they wanted us to count up to one thousand 43 is the same thing as ten hundreds and forty three so which of these numbers did we see when we counted from 43 to 1,000 43 well we didn't see 44 we didn't see 123 but we did see 143 so we did see 143 we saw 543 we saw 500 forty-three and we saw 843 so we saw these numbers now you might have been able to do this in your hand you might said okay 43 then 143 then 243 343 434 43 543 643 743 843 and then 943 and then 10 43 or 1040 3 either way these are the numbers that we found that we that we said when we counted from 43 to 1,000 43 or these are three of the numbers that we said
