Students use estimation as a math strategy. Students estimate the number of small snacks that are presented to them. Students count the snack items after they have estimated how many there are, before the class snack on a daily basis.

In this decimal activity, students solve a total of 31 decimal problems including: writing decimals, determining the smaller of 3 decimals, determining place value, rounding, filling in missing numbers and word problems.

Students figure out how to arrange seating in a concert hall given specific requirements. They better explain how dividing can allow us to arrive at mathematical solutions quickly and logically.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

Young scholars are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Learners compute the area of triangles in a computer program. For this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Students create a class timeline using the patent year for their selected inventor or invention. Using a piece of yarn, they physically create a timeline, and create and answer math word problems using the years from the timeline.

For this counting worksheet, students read about counting and when it is appropriate to find an exact count of something, versus counting by ten to find an estimate. They then read 10 items that can be counted and indicate whether they...

Students spend imaginary inheritance of $100,000 on a home and furnishings.

Students examine plant systems. In this life science lesson, students explore leaf and root systems on paper in a terrarium that they design and construct.

Students discover the advantage of estimation over simple guessing using number relationships. They also discover how useful a mathematical tool estimation is in everyday life.

Learners use candied hearts to estimate how many will fill the heart on the Valentine's Day themed page. They then do a final count after they have finished the estimation activities.

Students study grocery receipts to simulate the archaeological activity of classifying items. They discuss the receipts as if they were find lists.

Third graders get into groups of two. Next, give each student a piece of butcher paper that is long enough for them to trace their entire body. One person lies down while their partner traces the outline of their body. Upon completion,...

Young scholars utilize The Nature Park Adventure educational software program to Introduce Modelling, Including the Estimation of Angles.
