Mastery: Reasoning and Problem-Solving

  • Write the missing numbers:
    [____] + 4040 = 9099
    6166 – [____] = 6001
  • Draw a place value grid. Use digits 9 and 0 (you must use at least one of both) to create the largest and smallest 4-digit numbers possible. Use the same digits to write two numbers in between.
  • What is the largest possible 4-digit number whose digits add to 10? It must not contain a 0 and no two digits are the same. What is the smallest possible number like this?
