Bin It: Building Histogram From Data

Bin It: Interactive Grade 6 Histogram Worksheet (6.SP.B.4)

An interactive, auto-graded histogram activity where sixth graders sort real class data into bins themselves. Students tap a value chip, then tap the bar it belongs in, and a labelled brick lands on that bar. They can see every value they placed, tap a brick to send it back, and press Validate to check their work. When every brick is in the right bin, the stacks merge into a solid histogram. No drawing tools, no paper, no grading pile.

What students do

• Build four histograms from short class surveys: minutes to get to school, basketball points, bean plant heights and math quiz scores.
• Click to bin: tap a chip, tap the bar whose label includes that value. Each value becomes a brick showing its number, so students always know what they placed and where.
• Fix mistakes with one tap. Tapping a brick sends it back to the chip tray, and Clear all starts the histogram over.
• Press Validate. Bricks in the wrong bin turn red, and the feedback says how many chips are left or how many are misplaced. A correct histogram turns into solid bars.
• Answer read-off questions from their own histograms: how many values fall in a bin, how many are above or below a value, which bin is tallest, which bin is empty, and where the data bunches.
• Read a finished histogram with no raw data and decide what it can and can’t tell them, for example whether you can see exactly how many students sent 25 messages.
• Switch the same data set between bin widths 2, 5 and 10 and decide which width shows the shape best. A faint dot plot above the bars shows which values each bin groups together.
• Finish with a real decision: dot plot or histogram for the heights of all 340 students in a school, plus one reason.

Why teachers like it

• Auto-graded with a progress bar that fills as each problem is completed correctly. Only the final one-line reason is left for you to read.
• The labelled bricks make the idea of a bin concrete. Students watch individual values become counts, which is exactly the step where histograms usually lose them.
• Instant visual feedback: red bricks point straight at the misplaced values, so students fix their own work instead of waiting for you.
• The data covers three shapes: bunched at the low end, mound-shaped with a gap, and bunched at the high end. That gives you something to discuss beyond counting.
• Values sitting on the edges of bins (10, 15, 20, 70, 80) are built in on purpose, so students practise reading bin labels carefully.
• Hints only on Problem 1, then the scaffold comes away.
• Works on Chromebooks, tablets and laptops, and the tap targets are sized for touch.

Standards and fit

• CCSS 6.SP.B.4: display numerical data in plots on a number line, including histograms.
• Supports 6.SP.B.5a (number of observations) and 6.SP.A.2 (shape, clusters and gaps).
• Grade 6, 6 problems, about 25 minutes. Pairs well after Build the Dot Plot and before mean, median and spread.
