Outline
GED/ABE Mathematics Book 1 (ABE/preGED)
General Educational Development (GED) tests are a group of four subject tests which, when passed, certify that the test taker has American or Canadian high school-level academic skills. Here are some topics which can assist students in learning the mathematics covered on the GED/HiSET/TASC/GCSE General Certificate of Secondary Education.
Book 1 is a compilation of basic skills needed for success, but not tested. Mostly PreGED/ABE Skills
Book 2 has many activities which are tested. Many GED Level Skills
