Remind students to study the multiplication facts for the 2s, 3s, and 9s using the Triangle Flash Cards.
Use the Addition and Subtraction Quiz Assessment Master, the Feedback Box, and the Unit 4 Assessment Record to assess and record students' abilities on the following Expectations: Show that different partitions of the same number are equal using base-ten pieces, and number sentences (e.g., 200 + 30 + 7 = 200 + 20 + 17) [E1]. Represent and solve addition problems using base-ten pieces and number lines [E2]. Represent and solve subtraction problems using base-ten pieces and number lines [E3]. Solve addition and subtraction problems using mental math strategies (e.g., composing and decomposing numbers, counting up, and counting back) [E4]. Add multidigit numbers using paper-and-pencil methods (expanded form, all-partials, and compact) [E6]. Subtract multidigit numbers using paper-and-pencil methods (expanded form and compact) [E7]. Choose appropriately from among mental math, estimation, and paper-and-pencil methods to add and subtract whole numbers [E9]. Estimate sums and differences [E11].
- MPE1.
- Know the problem. I read the problem carefully. I know the questions to answer and what information is important.
- MPE5.
- Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
The Lesson 7 Workshop provides targeted practice.
