Grade 4 Math Topics

Fourth Grade

In the second trimester of the school year, fourth grade students will work on the following skills:

  • Division of up to 4-digit dividend by a 1-digit divisor
  • Finding equivalent fractions
  • Comparing and ordering fractions
  • Adding and subtracting fractions and mixed numbers with like numerators
  • Multiplying a fraction by a whole number
  • Finding equivalent fractions to decimals such as tenths and hundredths

You can help your child at home by having them practice these skills.  Continue to practice multiplication facts as well as this will make division much easier.  By the end of 4th grade students should know all of their multiplication facts through 12 x 12.     

Students continue to focus heavily on visual models for division, and fractions in 4th grade. For information on the area model used with division, you can view this video from Khan Academy about dividing a 3-digit number by a 1-digit number or view this video with dividing by place value which is another strategy students will explore By extending this area model which carries over the use or arrays for multiplication, students have been successful at dividing larger numbers with accuracy, and having an in depth understanding of what division really means as well as its connection to multiplication.

Helping students make a visual for finding equivalent fractions helps them understand why fractions are the same.  In school students have access to both hands-on and computer-based manipulatives for seeing the equivalence.  Students create number lines, bar diagrams, circles and fractions of a set of objects.
