Weekly Overview

Weekly Topics

 The focus of this week’s instruction is to deepen students’ understanding of:

  • place value
  • subtraction
  • addition

Materials Needed

  • Student Print Packets for each day
  • End of Week Assessment

Standards Covered

4.OA.A.3 Solve multi-step contextual problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

4.NBT.B.5 Multiply a whole number of up to four digits by a one-digit whole number and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Representations

  • Tape Diagrams:  Tape diagrams are also called “bar models” and consist of a simple bar drawing that students make and adjust to fit a word or computation problem.
  • Place Value Chart:  A place value chart is a diagram that helps us to find and compare the place value of the digits in numbers.
  • Standard Algorithm: standard algorithm or method is a specific method of computation which is conventionally taught for solving mathematical problems.

Additional Terms and Symbols

  • Bundling, making, renaming, changing, exchanging, regrouping, trading (e.g., exchanging 10 ones for 1 ten)
  • Difference (answer to a subtraction problem)
  • Digit (any of the numbers 0 to 9; e.g., What is the value of the digit in the tens place?)
  • Endpoint (used with rounding on the number line; the numbers that mark the beginning and end of a given interval)
  • Place value (the numerical value that a digit has by virtue of its position in a number)
  • Rounding (approximating the value of a given number)
  • Standard form (a number written in the format 135)
  • Sum (answer to an addition problem)
