K–12 teaching and learning · from the UNC School of Education

Goal 1

Number and Operations - The learner will read, write, model, and compute with non-negative rational numbers.

Objective 1.01

Develop number sense for rational numbers 0.01 through 99,999.

  • Connect model, number word, and number using a variety of representations.
  • Build understanding of place value (hundredths through ten thousands).
  • Compare and order rational numbers.
  • Make estimates of rational numbers in appropriate situations.

Exploring place value with M&Ms
This lesson will use M&Ms to explore place value. The students are given 8-10 M&Ms and assigned a value for each color from one to hundred thousand. The students will then write their number in standard, written and expanded form. The students will also identify the place and value of various digits.

Estimating rational numbers
Students round fractions and mixed numbers to their closest whole number by first changing the rational numbers into decimal numbers.

Does one cup of everything weigh the same?
The student will predict whether one cup of everything weighs the same. Next, the student will estimate the mass of several cups of materials. Then, using a primer balance the student will find the actual mass of each cup of materials in grams. The students will order the cups from lightest to heaviest by mass.
