Note: The team discussed wanting to start the year building on student proficiency with multiplication and division of whole numbers before jumping into the major work of fractions. We also want to support continued growth in adding and subtracting whole numbers which we will do through Number Talks and games. We feel a strong foundation with whole number operations will support sense making with fraction operations. The first unit in Investigations will support student conceptual understanding and procedural fluency with multiplication and division of whole numbers as the experiences build on models students were exposed to in fourth grade and provide an approach, time, space for students to make sense. Utilizing the "math workshop" structure will support an engaging math environment and allow us to build in time for math fact practice and to add in some addition and subtraction games. In order to utilize the related practice available in Math Expressions, we can use the first five lessons in each of Units 4 & 5 but will have to wait to use the remainder of those chapters as they focus on decimals. Be a critical connoisseur when looking at the 10 ME lessons in this area as they tend to be extremely procedural and often confusing (see my notes in the plan below).
In the plan below, the year is launched by revisiting Candy Boxes, a rectangular array investigation which they did in 4th grade. The purpose is to establish a math environment where students are deeply engaging in thinking, reasoning, looking for structure, making conjectures, and debating mathematics - regularly engagement in the math practices. It is also a familiar experience which the students will be able to take to a higher level than they were able to in previous years. It provides a review (and sometimes introduction) to multiplicative patterns and properties in the number system as well as key vocabulary.

Note: This unit has a pretty heavy procedural focus, often to the point of being flat out confusing. Nonetheless, there are some problem sets and homework pages that might be useful as long as you focus on students making sense and applying what they learned through the Investigations experiences. Lesson 1 Divide by 1-digit # I recommend not doing this lesson at all - confusing for students. partial quotients and the area model are much more understandable for students. Lesson 2 Divide by 2-digit # TE 397-402 Do not do PB 167! (very confusing) PB168 - the estimation focus here could be useful Lesson 3 Estimation (a pretty procedural approach to estimation - I recommend building estimation into your Number Talks and skipping this approach. Lesson 4 Interpret Remainders TE 409 PB 171-173 (a reasonable set of problems) Lesson 5 Division Practice PB 175-176 |
