Exhibitor Workshop for Singapore Math, Inc. April 17, 2015
Description:
During Singapore Math® implementation, gaps in student knowledge can be a challenge. Upper elementary students frequently lack the foundation provided by the 1-3rd grade Singapore Math® Curriculum. In this session, you’ll learn the classroom-tested critical lessons and concepts students must master before jumping into their grade-level content.

$1739 – $850 = $889
The oven cost $889
$1739 + $889 = $2628
Mrs. Coles paid $2628 for the
oven and refrigerator.
