Lessons

Lesson 1

From tally marks to a bar graph

Children read a tally chart, color a bar for each count, and use a bar graph to answer questions that put together or compare.

Lesson 2

Make a graph from counts

Children read the counts for four groups and color one box in the graph for each one. Then, with the teacher, they compare the rows of the finished graph: how many more, how many fewer, how many in all.

Lesson 5

Measure and make a line plot

Children measure pencils to the nearest inch, record ten lengths in a table, and show them as Xs on a line plot.

Teacher note

Common mistakes: Children draw one X for each different length, not one for each pencil, so three 6-inch pencils get only one X. Others stack the Xs unevenly, so a column of three looks taller than a column of four. When they number the line, some skip the lengths nobody measured.
Words to use: On the Ruler, set the units to inches and turn off "Show length." Leave the start handle at 0 and drag the end handle; the bar is the object. "Where does it end? Which inch mark is closest?" Read to the nearest inch. Then draw a number line from 2 to 9 on the board. Ten children each measure a used pencil to the nearest inch and say its length; draw each X above its number: "This pencil is 6 inches long. One X above the 6. Another 6: the new X goes on top of the first." Ask: "Which length do we see most often? How can you tell without counting again?"
What to watch for: On the easier page, the ten lengths are printed and the line is numbered: the child draws the Xs, one for each pencil, and answers the questions. On the page for everyone, the child also writes the missing numbers under the line; every tick mark gets a number, even where there will be no X. On the harder page, the table and the line are empty: the child measures ten used pencils with a ruler and numbers the line. Nothing printed on the page is to be measured. Have children cross out each length in the table as they draw its X, and count the Xs at the end: ten. For "how much longer," they count the spaces from the shortest to the longest.

Lesson 6

Each picture counts as two

Children read a pictograph in which each picture stands for 2 and write the real count for each row.

Unit check: before and after

Two short paper checks made from this unit's own worksheets. Give Check A before you teach the unit and Check B after it, and you can see what changed. Each part belongs to one lesson.

Part 1: Lesson 1, From tally marks to a bar graph (1 task)
Part 2: Lesson 2, Make a graph from counts (1 task)
Part 3: Lesson 3, Find a square on a grid (1 task)
Part 4: Lesson 4, Read a line plot (1 task)
Part 5: Lesson 5, Measure and make a line plot (1 task)
Part 6: Lesson 6, Each picture counts as two (1 task)
