Whole Number Foundations Level K

Whole Number Foundations Level K (WNF-K) is designed to accelerate the mathematics achievement of kindergarten students who are at risk for mathematics difficulties by focusing primarily on early number sense, numbers and operations, and vocabulary. The primary aim of WNF-K is mastery of number concepts and skills through the number 20.

• Tier 2 small-group intervention provided in addition to core (Tier 1) instruction
• 50 lessons delivered three to five times per week in 20-minute sessions
• Instructional objectives aligned with the Common Core State Standards in mathematics for kindergarten
• Research suggests WNF-K has a beneficial impact on student math achievement.
• The National Center on Intensive Intervention rated a study about the effectiveness of WNF-K as having “partially convincing evidence” regarding the study design, and “convincing evidence” regarding participants, fidelity of implementation, and broad math outcome measures.
• Available in Spanish as Fundamentos de los Números Enteros: Nivel K

Conceptual Framework

• Conceptual Understanding is developed through engagement with mathematical models including number lines, “nifty fifty” chart, ten frames, finger models, tally marks, and objects.
• Procedural fluency and automaticity
  • Systematic practice and review within and across lessons, with frequent opportunities for students to respond
  • Checks for mastery at the end of each activity
  • Math Practice worksheets help teachers monitor students’ mastery of concepts and skills
• Vocabulary and discourse
  • Key vocabulary is identified and explicitly taught and reviewed.
  • Scripted lessons ensure continuity and precise definitions.
  • Students are provided opportunities to use mathematical vocabulary to reason and provide justification.

Instructional Design Components

• Explicit scripted lessons. Lessons explicitly introduce important whole number concepts and skills concisely and consistently, emphasizing important math vocabulary. Lessons also provide frequent opportunities for students to respond, and scripted guidelines allow teachers to address potential misconceptions and reinforce mathematical language and vocabulary.
• Home-school connection. Each lesson includes a “note home” which summarizes the lesson’s concepts and skills, and provides suggestions to practice the math content at home.
• Math Check Points. Individually administered progress monitoring assessments that are administered every 5th lesson through lesson 25, and at lessons 34, 42, and 50.

Materials are available in two different formats:

• Convenient, downloadable PDF format. Once the PDFs are purchased, copies may be made according to the Distribution License Agreement.
• Pre-printed by the University of Oregon Printing Services Department.

Sample Lessons

• WNF K Sampler

Whole Number Foundations Level K includes 50 lessons divided into two Teacher Books, Math Practice worksheets, Program Support Materials, and a manipulative list.

• Teacher Book 1: Teacher’s Guide and Lessons 1 – 25
• Teacher Book 2: Lessons 26 – 50
• Math Practice worksheets
  • One Math Practice worksheet for each lesson
  • Math Check Point worksheets for assessing student progress after every 5^th lesson through lesson 25, and at lessons 34, 42, and 50
  • Math Check Point data sheets for recording student progress
  • One set of worksheets required for each participating student
• Program Support Materials
  • Reproducible masters of number cards, place value mats, ten-frames, and a number chart
  • Not sold separately
• Manipulative list: Manipulatives are required for implementation of the program and are NOT included. These manipulatives are commonly available in kindergarten classrooms, or may be purchased from educational retailers.

These products can be purchased together as an Intervention Kit. Additional and/or replacement Teacher Books and Math Practice worksheets may also be purchased separately.
