Demme Learning

A four-bucket palette layered over a semantic system, built for an education portal.

The design system Workhorse delivered to Demme Learning between November 2023 and August 2024. A complete brand foundation, four-persona research base, and the dashboard pattern for the Digital Toolbox product. The live build paused before launch. The system itself is the deliverable.

04 · Patterns

Composed patterns

Pattern assemblies that show how the components combine into surfaces. Built from the same tokens as the Foundations and Components above. The mobile top bar was the longest-running visual conversation in the engagement — six iterations to land the working frame.

Mobile nav · six states

The bar is constant across all six. The iterations are nav STATES — resting, open, and four section-expanded views. State 3 (Subjects) is the working frame: extending Math-U-See trust into the rest of the publishing portfolio.

The centerpiece. A LearnDash-shaped lesson surface — Bree Serif headline, the manipulative workspace that walks 43 minus 27 across orange ten-bars and green unit blocks, the orange-bordered Instructor Help card with its peach Lesson Solutions subcard, the Objectives / Why two-up, the problem set with status, the Warm Up + See It Solved band, the Beta progress strip, and the Instructor Note.

Subtraction with Regrouping

Build it with the blocks

43 − 27Manipulative cue

Build the top number with blocks. If the bottom digit is bigger than the top, exchange one ten-bar for ten unit blocks. Then take the bottom number away.

01Show 43
4 tens · 3 units
02Exchange one ten
3 tens · 13 units
03Take 27 away
1 ten · 6 units
43 − 27 = 16One ten-bar and six units left.

Instructor Help

When you are signed in as an instructor, anything in orange — buttons or shaded panels — is for your eyes only. Children see the lesson without it.

Orange means: print this, or open the solutions.

Lesson Solutions
Worked answers for every problem in this lesson.

The orange-shaded notes hold:

  • How to tell whether the child has the concept or only the procedure.
  • What to try when a child gets stuck on the exchange step.
  • Sample word problems you can read aloud at the table.
  • Optional questions for deeper, conversational practice.

Objectives Learning Goals

  • Subtract a two-digit number from a two-digit number with regrouping.
  • Trade one ten-bar for ten unit blocks when the bottom digit is bigger than the top.
  • Solve word problems that need regrouping in everyday situations.

Why? Learning Methods

Regrouping is what makes pencil-and-paper subtraction work. Once a child can exchange a ten-bar for ten units in the blocks, the same move on paper stops feeling like magic. The blocks teach the why before the digits ever touch the page.

Problem Set

  5. 0570 − 49—
  6. 0685 − 27—

Warm Up

Before you regroup, get the fact families warm. The Warm Up is a short stack of single-digit subtraction problems that show up later inside the borrowed column.

Complete the Warm Up in your Lesson Pages. If a problem stalls, tap See It Solved to walk through the blocks together.
