Daily Practice and Problems

The Daily Practice and Problems (DPP) is a set of short exercises that provides a structure for ongoing review and study of math concepts, skills, and math facts. To support this daily routine, at least two DPP items are included for each class session. The first item for a lesson is always a Bit and the others will be either Tasks, Challenges, or Bits. Nine icons designate the subject matter of the DPP items.

Problem of the Week

A DPP item that can serve as the Problem of the Week will be identified for every week of the unit and will always be a Task or a Challenge. The intention is that students be given a problem that allows time for thoughtful consideration of the strategies they are developing. Such a problem may require more reflection, maybe some trial and error, and may not be immediately solvable at first glance. At the end of the week students can share their strategies. The following DPP items in this unit can each serve as a Problem of the Week:

Task D in Lesson 1
Challenge T in Lesson 4

Review and Assessment of the Math Facts

Students have been developing strategies for solving the math facts since their early years and are fairly close to gaining or have gained proficiency. Students are expected to demonstrate fluency with the math facts cording to the following timetable.

  • By the end of second grade: addition and subtraction facts
  • By the end of third grade: multiplication facts
  • By the end of fourth grade: division facts

Many of the DPP items for this unit review the subtraction facts. DPP items for Unit 3 begin a systematic review of the multiplication facts.

Use DPP items E, M, Q, and S to assess students' fluency with the subtraction facts.

The first two assessments, Subtraction Facts Quiz: Count-Ups and Subtraction Facts Quiz: Count-Backs, contain subtraction facts that can be solved using counting strategies. The third assessment, Subtraction Facts Quiz: Using Tens, contains subtraction facts that can be solved by using ten as a strategy, and the last assessment, Subtraction Facts Quiz: Doubles and Others, contains items that can be solved using doubles.

These short assessments are less threatening and as effective as longer tests. Tests that include a small number of facts give teachers, students, and parents the information needed to continue learning and practicing the facts efficiently. The goal of the math facts assessment program is to determine the degree to which students can find answers to facts problems quickly and accurately and whether they can retain this skill over time.
