Standards-based assessment and Instruction

The instructional/formative assessment tasks in Problem Solving for the TEKS have been differentiated to include a "more accessible" and a "more challenging" version of the original problem. This feature allows teachers to meet the needs of students at various levels as they explore and practice new math concepts.

Austin and Eli have been saving pennies to buy a video game. Austin and Eli know the video game will cost 1,000 pennies. Austin has five hundred fifteen pennies. Eli has 400 + 30 + 5 pennies. Austin and Eli have some bags. Austin and Eli begin putting ten pennies in each bag. Austin thinks they each need to save twenty-five more pennies to have enough pennies to buy the video game. Is Austin correct? Show all your mathematical thinking.

## Here's What People Are Saying

In a number of recent studies comparing approaches to teaching mathematics in countries around the world, a list of 'best practices principles' have been identified. The Exemplars math program reflects the most important of these 'best practices principles,' and offers teachers a curriculum for teaching mathematics and assessing mathematical expertise from a contextual, problem focused point of view. The program is terrific.
