Basic Facts
• In how many ways can the number 4 be written as a sum.
• One example is 1+3=4• Figure out a way to record your
answers.
Challenge
• Sum can change depending upon the level students are at.
• When students master the skill move on to sum of 5.
Tangrams
• Try to form the letter E using all 7 tangram pieces.
• Try to form the letter T using all 7 tangram pieces.
• Try to form a dog using all 7 tangram pieces.
Exchange Game• You are playing an exchange game
where you have a mat for white, blue, and red chips. Five whites can be exchanged for one red chip, and five reds can be exchanged for one blue. You roll two standard dice. You take as many chips as you roll, put them on your mat, and when possible exchange whites for red or reds for blues. The first person to get two blues wins.
Possible Questions • How many rounds
would you expect this game to take?
• You have the amount pictured and you roll 8. What do you have at the end of this turn?
white red blue
• If you had the amount pictured, could you win on the next turn?
• Why or why not?
• How?
White Red Blue
Technology on line• National library of Virtual Manipula
tives• Songs for teaching• Math at Brevard• Math at Manatee
Estimation
• Look at the string with ten cheerios. How many cheerios will you need to make yourself a bracelet?
• Take a scoop out of the jar. Which has more the scoop or the jar?
Number Sense and Numeration
• Everyone at your table has made a string of ten cheerios. How many have been used in all?
Fractions • What fraction of the cheerios on
your string are red? On your necklace? In your jar are red? On your table?
• Ex. student answers are 3 out of 10.
• Students write it 3 10
Concepts of Whole Number Operations
• Linda made a string of ten cheerios. She holds it in her hand so that just 4 of them are showing. How many is she hiding in her hand?
Whole Number Computation
• Terry makes a pattern in which she repeats the colors red, yellow, red, green. If she used eight yellows, how many red cheerios did she use? How many cheerios in all?
Statistics and Probability
• Reach into the jar without looking and pull out ten cheerios. How many red ones do you expect to get? Try it 20 times and record the numbers. Make a graph.
Measurement
• How many cheerios do you need to make a bracelet to go around your wrist? To make a necklace?
Geometry and Spatial Sense
• What different shadows can a cheerios ring make? What other objects have the same shapes as a cheerios ring? What kinds of objects or figures are they? What do we call such objects.
Patterns and Relationships
• Look at your neighbor’s string. Can you predict what will come next? Why?
• What is your neighbor’s pattern?• How many units are in his/her
pattern?
Tips for Teachers of Mathematics
• Give clear and direct instructions.• Be repetitive and rephrase what
the book is saying for the sake of student comprehension.
• Be creative in using differentiated instructions and invite manipulatives into your lessons.
• Verify that students understand what they have to do before moving on.
• Welcome and encourage self-invented strategies by your students.
• Analyze how students arrive to their answers in order to correct mistakes and/or learn a new way of doing mathematics.
Remember the 4 Ss• Structure rules and routines • Stimulants manipulatives,
student related, fun etc.• Strategies self invent,
implement, give recognition• Skills prior skills, new skills, and
challenging skills
Rotten Apple Game• Start with 19 apples, and on each
turn you can take 1,2,3,or 4 apples. You lose if you take the last “rotten” apple. Try to discover a strategy for winning this game. Would you go first or second?
