Vermont Grade 2 Math

Seven strips, seven marks

An invented record gives seven paper-strip lengths measured to the nearest centimetre: 4, 5, 5, 6, 6, 6, and 7 cm. Make a line plot with equally spaced labels 4, 5, 6, and 7. Put one mark above the appropriate label for each strip. Explain how many strips have a recorded length of 6 cm and how the plot shows all seven strips.

Follow the reasoning

The plot has one mark at 4, two at 5, three at 6, and one at 7. There are three marks above 6, so three strips have a recorded length of 6 cm. Counting all the marks gives 1 + 2 + 3 + 1 = 7, matching the number of measured strips. The horizontal labels are lengths in centimetres; the marks count the strips with each recorded length. Stacking repeated marks keeps identical measurements visible instead of treating a repeated value as only one observation.

Check the explanation

These measurements are invented and rounded to the nearest whole centimetre. A recorded 6 cm does not establish an exact unrounded length of 6.000 cm. A line plot of lengths differs from a bar graph whose horizontal categories might name activities.

Try the next step

With teacher-approved materials and a ruler, measure several strips to the nearest whole centimetre and build a new line plot. Record the measurements first, use equally spaced whole-unit labels, and check that the number of marks matches the number of strips measured.

Vermont reference for this worked activity

The Vermont mathematics standards directory identifies Common Core State Standards adoption in 2010. The linked publisher PDF is the June 2010 CCSS mathematics edition; the upload directory date does not establish a new adoption. The agency also lists Vermont Early Learning Standards through Grade 3. Read the complete requirements and the school’s current curriculum sequence. The reference below selects one worked focus.

Choose a next task from the student’s explanation

Use a different set of numbers to check whether the student can explain the same relationship. If the explanation is unclear, return to the model; if the reasoning is sound but a calculation is wrong, work through a shorter calculation and check it against the model. Use the related learning resources alongside the teacher’s assigned goals.

The Vermont Agency of Education Academic Proficiency overview lists general VTCAP English and mathematics assessment in Grades 3–9. Grade 2 is below that listed mathematics range. Follow the school’s classroom assessment guidance. Independently published practice follows its own timing, tools, question count, and scoring; its result does not establish a state performance level. This original activity is not an official state assessment question. Read Vermont assessment guidance.
