A cow in a yellow sweater sits at a counter in a room full of cubbyholes: a giant sneaker, a little house, a jar of cookies, a cash register with buttons from 0 to 10. Click one and it opens into a game about counting, shapes, sizes or patterns, pitched at children of about two to six who cannot read yet.
Millie's Math House was Edmark's first Early Learning House title, released in 1992 and enlarged in 1995. This is the 1995 version 2.0 from the Macintosh side of the original CD, running on an emulated Power Macintosh under Mac OS 8.6.
Mac OS 8.6 starts and opens Millie's Math House by itself, in about a minute. Click any picture in Millie's room to go into that activity; the small picture in the bottom corner brings you back.

Edmark's House series passed from IBM to Riverdeep to Houghton Mifflin Harcourt, which retired the Edmark brand in 2017. This CD release of Millie's Math House has not been sold for more than twenty years. Full reasoning is in notices/millies-math-house.md, and the takedown promise applies without argument.

The 1995 program was written for the 68k Macs and early Power Macs of the time. It runs here on the same emulated Power Mac and shared Mac OS 8.6 system as Oregon Trail II and Word Munchers Deluxe, with its activities and voices on a small disk of their own, so it starts quickly and answers a click at once.
The activities
Everything is spoken and clicked; nothing has to be read. The activities on this disc are Cookie Factory and Number Machine (counting, and matching a number to a quantity), Little, Middle & Big (sizes, with shoes to fit three characters), Mouse House and Build-A-Bug (shapes, and putting a number of parts together), Bing & Boing (patterns to finish) and What's My Number.
Each has two modes, as the House series always did: click around freely and see what happens, or let the characters ask questions and answer them. Children can wander between rooms whenever they like, which is a large part of why it was so popular with parents and preschool teachers.
Why people remember it
Millie's Math House won MacUser's Editors' Choice for best children's program in 1992 and a string of education awards after it, and it sat on preschool and kindergarten computers for most of the decade. It was followed by Bailey's Book House, Sammy's Science House and Trudy's Time & Place House, and the series stayed in schools into the 2000s.
Here it runs as it did on a 1990s Mac, with nothing to install, which makes it easy to show a child the program their parent learnt to count with.
