Key ideas
Thousands, hundreds, tens, and ones each have their own place.
Add or subtract by place value, regrouping when needed.
Any number times 1 stays the same; any number times 0 is 0.
Break the bigger number apart by place value, multiply each part, then add.
A fraction of a whole names equal parts of one object.
Watch out for
- Dropping a zero placeholder, like writing 78 for 7 008.
- Misaligning the place values.
- Thinking a number times 0 is that number.

Key ideas
Rows and columns of a chart often repeat a pattern.
A symbol stands for the unknown number in a problem.
A multiplication chart has patterns like the doubling of a row.
The equation shows how the known and unknown parts relate.
A pattern in a table can be built with counters or blocks.
Watch out for
- Describing only one number instead of the pattern.
- Placing the unknown in the wrong spot.
- Missing that the pattern continues in both directions.

Key ideas
An analog clock shows time with hands; a digital clock shows numbers.
Area is how much surface a shape covers.
A 24-hour clock counts past 12, so 3 p.m. is 15:00.
We measure area by counting square units that fit inside.
A date can be written with the month name or with numbers.
Watch out for
- Reading the hour hand as the minute hand.
- Confusing area with perimeter.
- Forgetting to add 12 for afternoon 24-hour times.

Statistics and Probability
Graphs with Many-to-One Correspondence
Many-to-one correspondence
I understand that one symbol can stand for many items.
Official code: 4.SP1
Making and reading pictographs and bar graphs
I can build and read pictographs and bar graphs with a scale.
Official code: 4.SP2
The official wording · 2 outcomes
- 4.SP1
- Demonstrate an understanding of many-to-one correspondence.
- 4.SP2
- Construct and interpret pictographs and bar graphs involving many-to-one correspondence to draw conclusions.
Key ideas
In a graph key, one picture can represent several items.
If one picture means 5, then 3 pictures mean 15.
A pictograph uses a key; a bar graph uses a scale on the axis.
We read the scale to find how much each bar or symbol shows.
Watch out for
- Counting each symbol as one item.
- Ignoring the key's scale.
- Reading each bar unit as one instead of the scale amount.
