Day 7 - Working with Numbers

K-1 Activity:


Get some paper and make an empty number bond picture like the one pictured above.  You just need three circles.  Find some objects you can use such as, coins or cheerios.  See how many ways you can make 10 and write an equation for each way.

Gr. 2-3 Activity:
This activity is from openmiddle.com.
Use the digits 1 through 9 at most one time each to fill in the boxes to make the smallest or largest sum.


Gr. 4-5 Activity:
This activity is from openmiddle.com.
Use the digits 1 through 9 at most one time each to fill in the boxes to make the product as close to 7,000 as possible.

    Cecelia from FoxHill, I think the answer to the 2-3 challenge is
    99+99 for the highest number and 11+11 for the smallest number.

      Good thinking, Cecelia! That would work if you repeat digits. Can you try using each digit only once and see if you come up with some different numbers?

    Cecelia- For the 4-5 activity I think the closest equation to 7,000 using digits 1-9 is 81x86 and it equals 6966.

      Hi Cecelia, Nice thinking but remember you can only use the digits once and you used 8 twice. Try again.

    Cecelia-K-1 I think the answers are 0 + 10, 1+9, 2+8, 3+7, 4+6, 5+5, and all of those except 5+5 vice versa.

    Paige Finkel PG RM210: I think 97+86=183 is the largest sum because I used the two biggest digits, 9 and 8 for for the tens spot and the next biggest digits 7 and 6 for the ones spot. I did the same strategy for the smallest sum except I used the smallest digits. 13+24=37 is the smallest sum because I used 1 and 2 for the tens and then 3 and 4 (the next smaller numbers) for the ones digit.

      Hi Lauren, are you sure that is the closest? Keep trying to get even closer! Play around with the digits and values.

      That's really close but you used the number 8 twice. You can only use each digit once in the equation. Try again!

      HI Jack,
      That is close to 7,000 but you used the digit 8 twice. Try to use each digit only once.
