13) Number Track

Counting Backwards 10 to 1

71.1 Near Ten Strategy 9

Mathematics

  • Identify quantities of 1, 2 and 3 without counting.
  • Move a counter, jumping 1, 2 or 3 spaces on a number track.
  • Connect that moving left on a number track makes the number less.

Language

  • Move one/two/three spaces
  • Move left one/two/three spaces
  • Move right two spaces
  • “As you move left the numbers become less”
  • “You can see one, two and three without counting”

13) Missing Number Equations

Bonds of 5: Three in a Row, Fill a Row, Tic-Tac-Toe

Mathematics

Develop fluency using two-part bonds of 5 in related addition or subtraction equation where the unknown is a missing part.

Please Note: Please start with the ‘a little easier activities if students are unfamiliar seeing the missing number in a position other than the answer .

Language

  • addition as ‘add’. Read aloud as “(Part) add (part) equals 5”.
  • subtraction as ‘subtract’. Read aloud as “(Whole) subtract (part) equals (part)”.
  • equals
  • subtraction solved using adding on. For example, 5 – ? = 3 can be thought of as “What part joins (adds on) to 3 to make the whole of 5?”
