Pre-GED adult education math and numeracy slides (Part 2 of 2)

The Adult Ed Math Courses from Literacy Minnesota were developed for remote learning situations. This set focuses on pre-GED topics. The slides were designed to accompany a math textbook/workbook, namely Math Sense 2. However this is only a suggestion. The slides can work with any resource, online or on paper, that provides some additional practice for the concepts and strategies taught in the slides. A teacher guide and lesson template are also available.
