Students use Ohio census data to solve problems, make comparisons, draw conclusions, and support predictions related to Ohio's population. They interpret and work with pictures, numbers and symbolic information.

Students add and multiply decimals to complete gas choice worksheets. They discover which gas supplier has the best gas prices. Students collect and interpret data about local natural gas suppliers and use this information...

Students gather scientific data and be able to utilize the data to generalize results over a long period of time. They use the appropriate tools to measure quanities of liquids and analyze the data to determine the cost of a leaky faucet.

Young scholars, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

Students use ads from magazines to create data to be measured and apply the skill of estimation. They record the percentage of magazine ads that could be separated into different categories made by students through the use of logical...

Fourth graders complete multiplication, addition, and subtraction problems that all contain regrouping. In this regrouping lesson plan, 4th graders complete worksheets not provided.

Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...

Students listen to the problem read to them. They answer some simple questions using number sentences. They then compose a written record of the solution and share their approaches used.

Students attempt a problem that Students has the potential to have more than one solution. Hence the problem is accessible to a wide range of students. The problem is essentially about finding patterns and this is typical of a number of...

Second graders work on the problem with a partner. They examine what they are supposed to be doing. They share the students's solutions making sure than they are looking for patterns along the diagonals.

Fourth graders are introduced to the problem by weighing objects on the balance scales. Use weights in both pans. (If you don't have access to scales use 2 containers and a child acting as the balance.) They then listen to the problem...
