# Math Update for Nov. 5 – 8

November 4, 2018 by Kim Sorensen & Rebecca Farley

This week we will finish up multiples, factors, prime and composite numbers.  On Monday we will create factor posters, review Tuesday, and test on Wednesday.  On Thursday we will start multi-digit multiplication.

We have 4 weeks left of this trimester.  We will be working hard to pass math facts assessments and reviewing our concepts that we have learned so far this year.  I am proud of how hard our 4th graders have been working this year in math.

• 36 is the 9th multiple of what number?
• Is 3,456 prime or composite? Why?
• What are the factors of the number 50?

IXLs that match this week’s instruction:  IXL D.4, D.5, A.14, A.15

On Tuesday we will test on multiplication.  Students need to be able to show multiplication with arrays, pictures and repeated addition.  On Wednesday we will move on to division.  As we work with multiplication and division we are always using story problems that they need to make sense of.  3rd graders have been working so hard!  I look forward to everyone doing well on our assessment.
