Unit 3 Big Ideas

Students will be able to:

  • Read, write and demonstrate multiple equivalent representations for numbers up to 100,000 using objects, visual representations, including standard form, word form, expanded form, and expanded notation.
  • Compare whole numbers through the hundred thousands, and represent the comparisons using the symbols >, < or =.
  • Round a whole number to the tens or hundreds place, using place value understanding or a visual representation.
  • Add and subtract within 1,000 with or without regrouping.
  • Determine the reasonableness of whole number sums and differences in real-world problems using estimation, compatible numbers, mental computations, or other strategies.
  • Solve real-world problems involving two-step equations (involving two operations) involving whole numbers using addition and subtraction.

Unit 2 Big Ideas

Students will be able to:

  • Use drawings, words, arrays, symbols, repeated addition, equal groups, and number lines to explain the meaning of multiplication.
  • Multiply one digit whole numbers by multiples of 10 in the range of 10 to 90.
  • Use objects, drawings, arrays, words and symbols to explain the relationship between multiplication and division (e.g., if 3 x 4 = 12 then 12 ÷ 3 = 4).
  • Identify arithmetic patterns (including patterns in the addition or multiplication tables) using properties of operations.
  • Interpret a multiplication equation as equal groups (e.g., interpret 4 × 6 as the total number of objects in four groups of six objects each). Represent verbal statements of equal groups as multiplication equations.
  • Apply the commutative, associative, and distributive properties as strategies to multiply and divide.
  • Find the area of a rectangle with whole-number side lengths by modeling with unit squares, and show that the area is the same as would be found by multiplying the side lengths.
