Orchard baskets: multiply complete equal groups
A rectangular arrangement for a pear orchard has 1 row with 10 pears in each row. Change the controls and explain what the animation reveals.
Predict what will happen, press Play, then pause and explain what changed. Every control also works without playback.

Understand what you are seeing
The idea behind the motion.
A rectangular arrangement for a pear orchard has 1 row with 10 pears in each row. An array organizes multiplication as equal rows. Changing the order of the factors rotates the organization but preserves the number of individual objects. The complete rectangle contains 10 objects; a missing row would remove exactly 10.
A relationship to keep
1 × 10 = 10 objects
Read the symbols alongside the explanation. A diagram shows the relationship; the assumptions tell you when it applies.
- STEP 1
Read the starting situation
A rectangular arrangement for a pear orchard has 1 row with 10 pears in each row. Identify what each number measures before changing a control; the worked example refers to these starting values.
- STEP 2
Follow the mathematical change
Advance the timeline one full row at a time. Compare the running count with the equal size of each completed row. Pause on an intermediate frame and compare the picture with the live readouts.
- STEP 3
Explain and test the relationship
The complete rectangle contains 10 objects; a missing row would remove exactly 10. Change one input, predict its effect, and test whether the same relationship still works.
Your turn to explain
Make a prediction. Test your reasoning.
Orchard baskets: use the original situation. A rectangular arrangement for a pear orchard has 1 row with 10 pears in each row. What total would one additional full row produce?
Use the values specified in the question. Reset restores the initial values for this investigation.
Compare your explanation
20 objects, because 10 + 10 = 20.
