Cognitive Complexity Level: 1-Recall

[divider] [/divider] Students are able to… 

  • Given a set of objects, students can make as many groups of 100 as possible, then as many groups of 10 until no more can be made and then represent the amount on a place value chart.
  • Shown a number in standard form, students can read the number and describe it using place value language (625 is read as “six hundred twenty-five” and described as “6 hundreds 2 tens 5 ones”).
  • Read and write numbers in expanded form.

[divider] [/divider] Students are able to…because teachers:

  • Engage student in learning experiences where the count a set of objects by making as many groups of 100 as possible then as many groups of 10 as possible recording the number on the place value chart.
  • Pose questions requiring students to read numbers and use precise place value language when describing numbers.
  • Facilitate student discussions making connections between the various ways to represent a number (concrete modes, pictorial models, place value chart, base ten language, expanded form, words and numerals).

 [divider] [/divider] Questions to ask students:

  • Ask:  Write a number such as, 273 and ask student to read it to you.  Then ask students to write 273 in expanded form.
    • Sample answer that indicates understanding: “Two hundred seventy-three. 200 + 70 + 3”
  • Ask: students to represent 5 hundreds 3 tens 8 ones in three ways.
