4-5 practice writing a function rule answers to math

After a few examples, invite eager students to place the remaining blocks. The game continues so that many students are involved. Sorting with loops Place two loops of string on a large mat, overlapping as shown here. Four square regions that happen to be arranged in a square array could, of course, be totally independent.

The teacher thinks up a secret rule. Then the teacher offers the marker to a student, in a silent request to complete the pair.

Students who "see" the rule right away enjoy showing that they know it. Place a collection of Attribute Blocks -- in this case large and small squares and triangles of three colors -- nearby, but off the mat. A sorting rule Guess My Rule also works well with sorting rules.

After silently giving a few examples that obey the rule show the patternthe teacher offers eager students the chance to show not tell that they "got" the pattern by silently doing more of what the teacher had been doing.

Here is exactly the same sorting rule and four already-placed blocks, using a table instead of a pair of loops. The "secret rule" this time will be "small blocks in one loop, blue blocks in the other" and all other blocks must be set on the mat, but not inside either loop.

One might collect red objects, one green, one blue, and one yellow which would leave it empty in this example.

Guess My Rule

Sorting into a chart or table One can, instead, sort into a tabular arrangement. Without the labels, though, this form makes it harder to see that the four boxes are not four totally independent regions.

Why are labels more important on the tabular form than on the Venn form? Thus, Guess My Rule gives the teacher a good opportunity to reach students of different abilities. In a Guess-My-Rule game, the "labels" would be blank, so that the rule is not given away, inviting children to think about what might later be written on them.

Therefore, before playing the game in this tabular form, children need to have seen a table with labels e.

Graphing Functions

Mathematical communication tends not to use arrays in this arbitrary way, and so, over time, we come to expect arrays to carry the implication that the rows and columns "mean something. As the class catches on, other requests may work backwards, or be more challenging.

Resources Guess My Rule Guess My Rule games are games in which one person thinks up and gives examples of some "rule," and the player s try to discover the rules from the examples.

One by one, the teacher picks up a block and places it in the proper spot.


For more about this way of sorting, see Venn diagram. But children might -- quite scientifically -- not make such assumptions without evidence. When the teacher is leading, Guess My Rule games are particularly suitable for the Silent Teaching technique.Answers may vary.

Sample: lBED; the base angles of an isosceles triangle are congruent. Answers may vary. Sample: lBEC; all the angles of an equilateral triangle are congruent. 15; 90; 30 isosceles 69; 37 45 72 8 Yes, because the measure of the smaller angle is • Player B may guess the rule at any time by writing the rule in the rule space on the function machine and saying it aloud.
