3rd Grade Math Lessons 1-10

  • Lesson 1-Whole Numbers

    Understanding whole numbers, counting and place value. Reviewing some things we learned last year. Talking about rounding to the nearest 10 and 100.
  • Lesson 2- Addition and Subtraction

    Understanding place value and moving that into the understanding of adding and subtracting. Being able to use place value to understand lining up equations.
  • Lesson 3- Multiplication

    Using place value and properties of operations to understand multiplication of whole numbers in multiples of 10.
  • Lesson 4- Standard and Expanded Form

    Understanding how to read and write numbers in standard form. Understanding how to read and write equations in expanded form.
  • Lesson 5- Comparing and Ordering Numbers

    Understanding how to compare numbers through 999,999 using >,< and =.
  • Lesson 6- Beginning Fractions

    Beginning to understand fractions, what they are, and as numbers. (Using denominators 2,3,4,6,8,10). Understanding the representation of a fraction on a number line.
  • Lesson 7- Continuing Fractions

    Understanding fraction equivalence, demonstrating it on a number line. Using set, linear and area models. Understanding that whole numbers can also be written as fractions. (ie. 4/4=1, 4/1=4). Knowing fractions with the same numerator and denominator can be compared by reasoning their size based on the same whole.
  • Lesson 8- Mixed Numbers

    Develop an understanding of mixed numbers, still using denominators (2,3,4,6,8,10) as iterations of unit fractions on a number line
  • Lesson 9- Concrete Objects and Multiplication

    Using concrete objects, drawings or symbols to represent multiplication facts of 2 single-digit whole numbers and explaining the relationship between factors and product.
  • Lesson 10- Introductory Division

    Introducing Division without remainders using concrete objects, drawings and symbols. Explaining the relationship of whole number quotients, divisors and dividends.
