Building Number Sense

Traditional Arithmetic & Logic

The sequenced K–5 mathematics series of the Faith Thinkers family.

Kindergarten through Grade 2 also include a coordinated practice workbook and a complete teaching guide; Grades 3–5 pair their student texts with the extensive Math Practice Library.

Core math curriculum · Who it is for

Is Building Number Sense the right math program?

Building Number Sense is the lesson sequence of the Faith Thinkers family; the Math Practice Library is the practice. The two stay distinct on purpose, so you always know which one you are holding.

Choose it when

  • You want traditional arithmetic taught in order from a student text — the model shown clearly before the child works alone.
  • You are teaching Kindergarten through Grade 2 and want the full package: student text, coordinated practice workbook, and a teaching guide you can read in full before you join.
  • You are teaching Grades 3–5 and want a sequenced student text supported by extensive grade-and-skill practice in the Math Practice Library.

More Faith Schooling paths

  • You already have a math program and only need more practice pages by skill — the Faith Thinkers Math Practice Library.
  • You want to inspect the exact grade package first — every grade page shows the real student text, included components, skills, and eight zoomable sample pages.

Questions parents ask

What is published for each grade?
All six Kindergarten through Grade 5 student texts are published. Kindergarten, Grade 1 and Grade 2 also include a coordinated practice workbook and complete teaching guide. Grades 3 to 5 are supported by the extensive Math Practice Library, organized by grade and skill.
How is this different from the math practice library?
This is the curriculum — it decides what is taught and in what order. The practice library is drill and review for a skill that has already been introduced. Most families use both, but the practice pages are never the lesson.
Do I need manipulatives?
Nothing you have to buy. The concrete stages call for countable objects, and beans, buttons, coins or pasta all work. What matters is that a child moves real objects before working with the symbols.
Where do I start if my child is behind in math?
Start at the skill, not the grade. Print the free sheets from a set one grade below your estimate; if they are comfortable, move up, and if they are not, you have found the starting point. Every practice set opens its first three sheets to everyone.

Real, zoomable previews

Eight substantial sample pages per grade show the level, layout, modeling, computation, and reasoning your child will encounter.

Kindergarten through Grade 5

Choose a grade to inspect the actual work

Every grade page provides the cover, scope, component list, and eight hand-picked previews from across the student text.

Curriculum and practice stay distinct

Need more practice after the lesson?

Building Number Sense is the sequenced textbook series — the lessons. The separate Faith Thinkers Math Practice Library holds thousands of practice pages organized by grade and skill for review, reinforcement, and independent work; it supports the lessons and never replaces them.
