Mathematical Standards

2.NBT.A
Understand place value. (2.NBT.A.1, 2.NBT.A.2, 2.NBT.A.3)
2.MD.B
Relate addition and subtraction to length. (2.MD.D.6)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.
MP5.
Use appropriate tools strategically.
MP6.
Attend to precision.
MP8.

This Workshop reinforces the place value activities of earlier lessons. Students practice showing numbers partitioned into hundreds, tens, and ones by drawing hops on the number line, modeling with connecting cubes, and writing number sentences.

Content in this Lesson

  • Representing quantities (to the hundreds) using connecting cubes and symbols [E1].
  • Composing and decomposing numbers using ones, tens, and hundreds [E2].
  • Showing different partitions of numbers using connecting cubes, number lines, and number sentences [E3].
  • Making connections between place value concepts and representations of numbers with connecting cubes, number lines, and number sentences [E6].
  • Recognizing that different partitions of a number have the same total [E7].
  • Solving addition and subtraction word problems involving two or three whole numbers using number lines, number sentences, or 200 Chart [E8].

E1. 
Represent quantities (to the hundreds) using connecting cubes, words, and symbols.
E2. 
Compose and decompose numbers using ones, tens, and hundreds.
E3. 
Show different partitions of numbers using connecting cubes, number lines, and number sentences (e.g., 154 = 100 + 50 + 4).
E6. 
Make connections between place value concepts and representations of numbers with counters, number lines, number sentences, and symbols.
E7. 
Recognize that different partitions of a number have the same total (e.g., 50 + 4 = 40 + 14).
MPE5. 
Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
