Why number lines? A solid understanding of number sense and place value is absolutely critical as we move our students forward in their mathematical thinking. This is true for fractions and decimals too! We often expose students to numbers in a variety of ways…using manipulatives, using 100’s charts, and so on. One area that is often overlooked is the building of understanding of how numbers relate to each other and how they “fit” with other numbers.
For example…students may have a solid understanding of what “10” is and how to model it—but they don’t always realize what “10” means compared to other numbers…that 10 is half of 20…and double 5…and closer to 0 than to 100 and so on! In my attempt to really help my students understand place value AND develop their mathematical practices, I have developed these resources and share them with you now! THIS edition focuses on numbers through fractions and decimals
What is included?
This resource has a number of different elements to help you tackle place value--including 8 pages of information, teaching tips, and photos of the resource in action! The problems start off simple to help build that foundation and then gradually get more and more sophisticated and include fractions less than 1, mixed numbers, and decimals.
It includes 80 ready-to-copy math journal problems (5 per page) that ask students to either identify a mark on a number line or to make a mark at a certain point on a number line. These are NOT meant to be exact answers—but for students to use their number sense to come up with reasonable solutions. What is CRITICAL is the second part—”Explain your thinking!” Whether students work together or alone, the problems ask them to defend their solutions. There are problems at a variety of levels…you will notice that they start easier and get more sophisticated—including a set of pages where the number lines do not start at 0. Look through and see which problems are the right level of challenge for your class—and consider differentiating by giving different groups different problems.
Also included is a set of 10 pages that can be used as either homework or assessments! Students are asked to do the same types of problems as used in math journals, but are asked to work on them independently. The pages increase in difficulty as their number increases.
A simple rubric to help you assess how well your students are able to “Construct viable arguments” and a class checklist to record progress. An answer key with suggestions is also included.
NOTE: This is a challenging resource geared toward helping grade 4-5 teachers "raise the rigor" of their math instruction. Differentiation tips are included!
