Lesson 2:

State Standard: 4M2, 4M4, 4M5, 4M6, 4M7

Open Response: (5 min.)(Give the problem and let the students try to figure it out writing their solutions onto paper. After a few min. share their solutions)

My dog is taller than my cat.

My cat weighs more than my dog.

My dog drinks more than my cat.

Show how tall my dog and cat might be, how much they might weigh and how much they might drink.

State Standards Practice:(25 min.)

Measure Length & height          (to 1/4 inch & cm.)                   4M2

Mass                            (grams and kilograms)               4M4, 4M5

Capacity                       (milliliters (ml.s) and liters)                     4M6, 4M7

Provide students with access to the following, preferably at least one set per group.

·        12 inch & 30cm ruler

·        Scales to measure grams and kilograms

·        Measuring cup set (cup, pint, quart, gallon)

·        Counters to use in measuring (bears, blocks, cubes, etc.)

Have students measure 2 differently shaped open containers that are similar in volume. Try to find one that is short but fat, the other tall but thin.

Ask students to work out which is bigger.

Brainstorm how they could do this. (Measure length, height, mass, volume

Have students measure length, height, mass and volume of each.

Discuss findings. Which is bigger? Does bigger mean Heavier? Larger Volume? Taller? Wider?

(Note there is no real correct answer to this. Have students engage in discussion)

Lesson 3:

State Standard: 4M8, 4M9

Open Response: (5 min.)(Give the problem and let the students try to figure it out writing their solutions onto paper. After a few min. share their solutions)

I had breakfast last Saturday 3½  hours after I woke up. What time might I have woken up and what time might I have had lunch?

State Standards Practice:(25 min.)

Draw an analogue clock onto a blank page.

Draw what time you like to have lunch.

Write underneath the clock what this time looks like on a digital clock.

Write what time you like to have dinner.

How long is it between having lunch and having dinner?

What about between Breakfast and Lunch.

Which is longer?

Have students work out how long it is until

a)      their birthday

b)      the end of the school year

c)      dates of their own choosing

In both weeks and days, and just days.

Share.

Lesson 4:

State Standard: 3S2, 3S3, 3S4, 3S5, 3S6, 3S7, 3S8

(Note: All Grade 4 Statistics and Probability Standards are Post-March)

4S3, 4S5, 4S6

Open Response: (5 min.)(Give the problem and let the students try to figure it out writing their solutions onto paper. After a few min. share their solutions)

The graph in the paper showed more people liked Blue M&M’s that green.

What might this graph have looked like?

State Standards Practice:(25 min.)

Open a bag of M&M’s and record the number of each color onto a Tally Chart with the following headings.

Color   Tally     Total

Place onto an Overhead Projector making a pictograph of the colors.

E.g.,     Blue       ●●●●●●●

Green     ●●

Yellow   ●●●●●

Etc.

Have students draw a Bar graph showing the colors from the bag.

Share.

Predict the number of each color in a second bag of M&M’s.

Have students record their predictions.

Have each student create a tally chart as you say each color as you draw M&M’s from the bag one at a time.
