Unit 6: Division, Coordinate Systems and Measures of Angles

During Unit 6, students apply basic division facts and use them while performing traditional long division.  They learn how to use the mnemonic phrase, "Does McDonalds Sell Cheese Burgers?" to remember the steps of long division.  The D in Does stands for divide, the M in McDonalds stands for multiply, the S in Sell stands for subtract, the C in Cheese stands for Compare, and the B in Burgers stands for Bring down.  When remainders are present, they will discover how to write them as fractions and decimals.  In addition, they will apply their division skills when solving multiplication number stories and learn how to interpret remainders.  Fourth-grade mathematicians will also review coordinate systems and learn how to measure angles in degrees.

The four main areas of are:
  1. To practice solving multiplication and division number stories,
  2. To introduce the traditional division algorithm and the concept of remainders and fractions or decimals,
  3. To practice drawing, measuring, and naming angles using half-circle and full-circle protractors, and
  4. To utilize letter-number pairs and ordered pairs on a grid system.
It will remain important through this unit for students to continue to practice their basic multiplication and division facts daily.
