This short video and interactive assessment activity is designed to teach fourth graders about using the four operations with money - word problems.
This short video and interactive assessment activity is designed to teach third graders about understanding division with remainders and illustrations.
This short video and interactive assessment activity is designed to teach fourth graders about place value problems involving money.
This short video and interactive assessment activity is designed to teach second graders about using timelines to 1-minute increments.
This short video and interactive assessment activity is designed to teach fourth graders about adding and subtracting - missing number.
This short video and interactive assessment activity is designed to teach fifth graders about adding and subtracting - missing number.
This short video and interactive assessment activity is designed to teach fifth graders about adding and subtracting with parentheses - missing number.
The goal of this task is to provide examples for comparing two fractions by finding a benchmark fraction which lies in between the two.
This task highlights a slightly different aspect of place value as it relates to decimal notation. More than simply being comfortable with decimal notation, the point is for students to be able to move fluidly between and among the different ways that a single value can be represented and to understand the relative size of the numbers in each place.
This short video and interactive assessment activity is designed to teach third graders about using timelines to 1-minute increments.
This short video and interactive assessment activity is designed to teach fourth graders about using timelines to 1-minute increments.
Students develop a physical understanding for the meaning of equality by trying to find equal lengths using rods.
This task helps students broaden and deepen their understanding of the equals sign and equality.
This task asks students to write and interpret a given expression.
This problem asks the student to evaluate six numerical expressions that contain the same integers and operations yet have differing results due to placement of parentheses. It helps students see the purpose of using parentheses.
Students collect a large set of data (approximately 60 sets) of individual student’s water use and learn how to use spreadsheets to graph the data and find mean, median, mode, and range. They compared their findings to the national average of water use per person per day and use it to evaluate how much water a municipality would need in the event of a recovery from a water shutdown. This analysis activity introduces students to the concept of central tendencies and how to use spreadsheets to find them.
Students apply their knowledge of scale and geometry to design wearables that would help people in their daily lives, perhaps for medical reasons or convenience. Like engineers, student teams follow the steps of the design process, to research the wearable technology field (watching online videos and conducting online research), brainstorm a need that supports some aspect of human life, imagine their own unique designs, and then sketch prototypes (using Paint®). They compare the drawn prototype size to its intended real-life, manufactured size, determining estimated length and width dimensions, determining the scale factor, and the resulting difference in areas. After considering real-world safety concerns relevant to wearables (news article) and getting preliminary user feedback (peer critique), they adjust their drawn designs for improvement. To conclude, they recap their work in short class presentations.
When a division problem involving whole numbers does not result in a whole number quotient, it is important for students to be able to decide whether the context requires the result to be reported as a whole number with remainder or a mixed number.
This short video and interactive assessment activity is designed to teach second graders about which amount is not equal to a given amount of money?.
In this task students compare 4/5 to 5/4 on a number line.
