Activity 1: Begin by distributing a hundred chart to all students and
discuss how it is constructed; ask students to talk about any patterns they
see (rows of 10, columns of 10, etc.). Tell students that by following with
their pointer finger on the chart, they are going to listen to a set of
clues, do some mental math by adding or subtracting, and try to end up at
the designated number. Example: “Start with the value of a penny, Plus 10,
Add 3, Take away 2, Plus 20,” etc. The teacher verbally states each clue
with a short pause in between, and after around a dozen clues, asks students
to name where they are on the hundred chart. Repeat activity, only this time
increase clues to around 16, and instead of having students tell the number
at the end, have them describe the number using math vocabulary. Now have
students use pointer from both hands, and give clues for each with the
object being to end up with both fingers pointing at the same number.
Example: “One start on the value of a penny; the other start on the value of
a dollar, To the smaller add 22, From the larger minus 20,” etc. Again ask
students to give a verbal description of the number. Ready made scripts for
these can be found in Mental Math with Tiles & The Hundred Chart by Marcy
Cook.

Activity 2: Distribute pre-made “I Have” clues to each student. Teacher begins by asking the first clue. Example: “Who has the square of 7?” The student who has the answer, 49, must say, “I have 49. Who has…” and continue reading their clue. The student with that answer must respond accordingly, and the activity continues in this fashion until every student in the room has verbally participated and the game has gone full circle so that the last clue leads back to the student with the first answer. Teacher can follow the script, but only students giving clues and answering clues may speak. After completing a round, shuffle clues and redistribute. (Students like the challenge of trying to complete the round in a faster time. This activity can be designed to review almost any math concept.) Ready made scripts for these can be found in I Have by Marcy Cook. |

Activity 3: Display overhead transparency of problem utilizing Guess and Check Strategy. Read the problem to the students and elicit verbal responses for guesses. Through verbal questioning, lead the students toward the answer by helping them discover that they need to start with a reasonable guess, check to see if it is correct, and continue eliminating possibilities as they get closer to the solution that fits the given clues. Display second problem, have students partner up, and allow them to talk together to find their answers. Have volunteers verbally explain their strategies to the class. |
