  3. True or False – all the common multiples of 4 and 7 are odd. Explain your answer using your reasoning skills.

      Girls, just like the factor bugs or Venn diagrams we have done in class you should be able to see which numbers are not multiples of 4 and 7. Do it in a systematical order.

      1 – if you have filled the first part of the grid you need to list the first 4 multiples of 4 and 7.
      2 – look at all these numbers that are multiples of 4 and 7 are they odd or even or both.

      If you need more guidance ask me in class tomorrow.
