This problem requires a sound understanding of the fraction relationship between part and whole and can be used for finding fractions of numbers and quantities. Students are given the fractional amount of apples in a fruit bowl and the specific number of other fruit in the bowl in order to figure out how many apples are in the bowl. The Teachers' Notes page includes suggestions for implementation, discussion questions, ideas for extension, a link to a worksheet which provides student support, and a downloadable pdf of the puzzle.

This problem provides students practice in fractions (tenths) and challenges students' addition and subtraction skills. Students are given a cake with the numbers zero to nine on it. They are asked to cut the cake into three pieces with three cuts so that the numbers on each piece add to the same total. The Teachers' Notes page offers rationale, discussion questions, ideas for extension and support, and a printable (pdf) worksheet of the problem.

This is a lesson plan designed to deeped understanding of real world, multistep math problems for the 5th grade.  It could be adapted to any grade level.  Students will need to understand basic math operations and apply them to either act out a real world problem, or act as the teacher and take a deep dive in how to solve the problem presented.  It is designed mostly to use with metric and customary conversions, but could be applied to any real world problem.

This problem provides students an opportunity to find equivalent fractions and carry out some simple additions and subtractions of fractions in a context that may challenge and motivate students. Users need to download, print, and cut-out the fraction jigsaw. Then, they must arrange the square pieces right-side up so that the edges that touch contain equivalent fractions. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.

This problem provides an interesting context to consolidate addition of fractions and requires students to develop and analyze different strategies and explain their findings. Students are asked to find a general method for expressing unit fractions (fractions which have numerators of one) as the sum of two different unit fractions. They also explore whether all unit fractions can be written like this in more than one way. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.

Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.
