Which of the following options show the correct tally chart to sort these shapes?
Open in App
Solution
The correct option is C
Say: On our screen, we have two rows with hearts and stars. To make a tally chart, every time we see a star, we draw a line for the star. Similarly, every time we see a heart, we draw a line for the heart.
Let us count them.
Steps:
The first shape we see is a heart. So, put one line in the tally marks column for the heart.
Next, we see two stars. So, draw two lines in the tally marks column for the star.
Now there are three hearts; so, draw two lines and a cross off at the fifth count.
Continue counting in the same way till all the shapes are counted.
We count 9 stars and 6 hearts.
Option A does not have a cross off at 5th count. Hence, it is incorrect.
Option B also does not have the correct tally lines. Hence, it is also incorrect.
Option C has 9 stars and 6 hearts, all correctly marked. Hence, it is correct.
Option D has does not have the correct tally lines. Hence, it is also incorrect
Hence, Option C is the answer.
WB: If required, use the whiteboard to count each shape one at a time as it comes, and draw a tally chart as shown.
Probing Q: Option A has 6 and 9 lines. That’s how many hearts and stars present. It is also correct. Let us mark it correctly. Shall we?
A: No! After every 4 rods, the fifth is marked as a slash to depict 5 counts. This is the rule of the tally chart.
