Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).

Surf's up! Kids help Floyd ride a huge wave by typing accurately and quickly in this fast-paced, fact-filled keyboarding game. As they learn about Sojourner Truth, interesting places, and taste buds, they'll practice combining tons of different letters and combinations. The more kids practice typing, the more familiar they'll become with various letter, number, and symbol combinations.

When students learn the patterns and structures of words they become word wizards! They are able to more fluently convert a word from one part of speech to another, adjust the meaning, or translate a word from singular to plural (or vice versa). In this set of activities students will build on their knowledge of word structure and practice adding prefixes and suffixes, changing tenses and using contractions.

Calculating the volume of rectangular prisms is a new skill that is introduced in 5th grade. Students will apply mathematical formulas to find the volume of different kinds of figures and also determine the volume of a figure composed of two connected rectangular prisms. Learners will also work with other kinds of measurement when they make larger or smaller versions of figures (to scale) and learn to convert measurements.

Representing data on graphs makes math visual and involves some creativity and design. Plotting data using fractional units takes their learning one step further. Also in this unit, students learn to measure using both traditional units (like inches, feet and yards) and metric units, and how to convert measurements within each system. The concept of measurement gets two dimensional when students explore measuring and working with angles.

This guided geometry lesson takes second graders on an exploration of 2D and 3D shapes. Kids will learn how to sort shapes, as well as partition them into halves, quarters and thirds. Tangrams are also featured within the exercise in order to give kids practical ways of practicing their new geometry skills.
