Workshop: Place Value Practice
Est. Class Sessions: 2Before the Lesson
Review student work and progress from previous lessons to guide instructional decisions about the following Expectations:
- 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).
- E8.
- Solve addition and subtraction word problems (e.g., adding to, putting together, comparing) involving two or three whole numbers using number lines, number sentences, or the 200 Chart.
In this Workshop, students will further develop their flexibility and confidence representing partitions of numbers using different representations. In Part 1, the Spin a Number Game is introduced to the class using 2-digit numbers. All students need to develop confidence with using number lines, number sentences, and connecting cubes to represent partitions of numbers. In Part 2 of the Workshop, students are introduced to the Place Value Practice Workshop Menu. They use it to guide their practice choices. Students work to solve as many problems as they are able on the Show the Number pages in the Student Activity Book. Then students play their version of the Spin a Number Game. Students having trouble with partitioning numbers into tens and ones should work only with two-digit numbers, i.e., only the tens and ones spinners. Students who are confident partitioning numbers into tens and ones can work with three-digit numbers and use all three spinners.
