Kit A

Students represent basic addition and subtraction facts with models, in number sentences, and from memory. The system of tens is explored through rounding, patterns, and place value. Estimates are analyzed for reasonableness, ordinal and cardinal numbers are compared, and real-life problem situations are investigated. Manipulatives such as collections, connecting cubes, and counters are included.

Kit B

Students explore place value to four digits, compare whole numbers using words and symbols, and build models to represent multiplication and division. Problems are solved with and without regrouping. Number properties, fractions, and probability are explored. Spinners, fractional shapes, and number charts are included in the kit.
