EveryDay Math
Grade 5
Unit 2 - Estimation and Computation
Lesson Objectives
2.1 - To develop estimation strategies when finding an exact answer is impractical.
2.2 - To review place-value concepts and use of the partial-sums and column-addition methods. (Students are encouraged to use the addition algorithm with which they are most familiar.)
2.3 - To review the trade-first and partial-differences methods for subtraction. (Students are encouraged to use the subtraction algorithm with which they are most familiar.)
2.4 - To review the use of mathematical models to solve number stories.
2.5 - To provide experiences with estimating reaction times and with using statistical landmarks to describe experimental data.
2.6 - To review vocabulary associated with chance events and to introduce the Probability Meter.
2.7 - To provide experiences with making and using magnitude estimates for products of multidigit numbers, including decimals.
2.8 - To review the partial-products method for whole numbers and decimals. (Students are encouraged to use the multiplication algorithm with which they are most familiar.)
2.9 - To review and provide practice with the lattice method for multiplication of whole numbers and decimals. (Students are encouraged to use the multiplication algorithm with which they are most familiar.)
2.10 - To provide experience with comparing the relative sizes of 1 million, 1 billion, and 1 trillion and using a sample to make and estimate.
Note: Lessons are typically covered in one class period. Lessons 2.1 - 2. 10 will be followed by a review lesson, and then a summative assessment of these skills. Formative assessments may be given throughout the lesson to help students gauge how well they are mastering the lessons, and when they need to seek out additional help from me. Students seeking additional support should sign up for that help during “Quiet Time.”
