Bit by Bit Measuring

Formative Assessment:

What are different ways we can measure?

What tools or instruments are used to measure length?

Instructional Strategies or Activities:

Explain to students they are going to draw lines using a centimeter rule. Pairs of students use a game board in the shape of a large S. Each student has a die, colored pencil, (not the same for each student) and a ruler. The first student rolls the die and follows the code:

1= l cm

2= 2 cm

3= 3cm

4=4 cm

5=5cm

6= 0 cm

The first student draws a line the length according to the code. Player 2 takes a turn in the same manner. Each player must draw the entire line. A line may not be broken. If a line cannot be drawn the turn is lost. The first player to reach the end wins.

Summative Assessment:

Teacher observation during the activity, then have a worksheet where students draw 10 lines of various lengths.

All 10 lines drawn correctly 10 pts.

8-9 lines drawn correctly 9 pts.

6-7 lines drawn correctly 7 pts.

5 or less drawn correctly 5 pts. (redo assignment)
