NumberSense Mental Arithmetic Learner Booklet 21
This booklet is designed for use during mental arithmetic sessions where the teacher calls out each calculation and children write only the answers in their booklets. The teacher should set a pace that suits the age and grade level of the class or group. The goal is for the children to answer the questions mentally using appropriate strategies. After each session, children can use the progress table on the back inside cover to record their fluency (how many are attempted) and accuracy (how many are correct).
These booklets are available for Workbooks 13-24. Teacher prompts and notes for these activities are available on the website.
This booklet contains suggested activities aligned to the corresponding NumberSense Workbook. The teacher has the flexibility to use the mental arithmetic items from previous mental arithmetic booklets. The progression of all the mental arithmetic calculations for all the booklets provides additional practice of the calculation strategies in the NumberSense Workbooks, and provides ongoing practice of the foundational manipulating number skills.
Each booklet contains 48 tasks. Within each task, questions are grouped in sets of five, with each set designed to reveal the application of one or more strategies.
