Greater, less, equal

Compare counts and numerals, including equal amounts and zero.

Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.

1. What you will learn

Tell which count is greater, which is less, and when counts are equal.

2. Comparison words

3. Match before deciding

Make a row of four counters and a row of six. Pair one counter from each row. Two counters in the six row have no partner. Six is greater than four. Four is less than six. The words change when you change which group you name first.

4. Use numbers, not space

Three large buttons may take more room than five small buttons. They are still fewer buttons. Pair them or compare their counts. A number said later when counting from zero is greater. Equal groups leave no extra object when paired. An empty group has zero objects; it is less than a group with any objects. Changing spacing does not change a count.

5. Compare four and six.

1. Pair four with four. [A group of four and a group of six counters]

   4 pairs

   One object from each group belongs to each pair.

2. Find the extra objects.

   2 extras; 6 is greater

   Only the six group has unpaired counters.

6. Compare five with five.

1. Match each counter once.

   5 pairs

   The counts are the same.

2. Your turn: work this step out. Its working is at the end of the packet.

   Look for anything left.

7. Guided practice

Which number is greater: 8 or 9?

• 9
• 8
• They are equal

8. Guided practice

One tray holds 9 big blocks. Another holds 9 small blocks. Compare their numbers of blocks.

• equal numbers
• More big blocks
• More small blocks

9. Practice

Two bags hold 5 and 11 counters. Write the smaller count, then the greater count.

Smaller: _s. Greater: _g.

10. Somewhere new

Put these new score cards in order, least first.

Number the steps in order (write the number in the box):

• 3
• 7
• 11
• 15

Audio transcript: None

11. Lesson test

Lesson test: one question per skill, one attempt each, no hints. Your answers are checked when you submit.

12. Test question

Two bags hold 2 and 6 counters. Write the smaller count, then the greater count.

Smaller: _s. Greater: _g.

13. What you can do now

Compare seven counters with seven larger counters. Does the size change their number? Explain.

Working for the steps left to you

6. Compare five with five., step 2
