Division as Equal Sharing (making equal groups)


Division as equal sharing: There is a total number of objects. For example 1, there was a total of 16 oranges. Then you put the objects into equal groups. For example number 1, it says there are 4 families making 4 different groups. The 16 oranges are placed in one at a time into each of the groups until all of the oranges are gone. The answer to the problem is the number of oranges in each group. For example number 1 the answer would be that each family gets four oranges. The same happens for the other two examples. There is a total number of objects that are place into the groups one at a time until all of the objects are used. The answer to the division problem is how many objects are in each group.

Relate Division and Subtraction

Lesson 1 Ex2.
Using a number line to divide, you start at the number that is being divided. Then you count backwards by the number you are dividing by. Your answer is how many times you had to subtract. In this example the problem was 21 divided by 3.  You would start at 21 and count backwards by three on the number line until you reached zero. You would subtract 7 times making the answer be 7.


For this example you would start at the number being divided and subtract by the number you are dividing by until you reach zero. This is also called repeated subtraction. The answer to the problem is the number of times you subtracted. Again the problem is 21 divided by 3. You would start at 21 and continue to subtract three until you reach zero. The number of times you subtract is your answer. In this example it shows that you would subtract 3, 7 times making 21 divided by 3 equals 7.

Relate Division and Multiplication


We focus on arrays, equal groups, repeated addition, and repeated subtraction. The goal is to recognize how division and multiplication are alike. This helps identify fact families (3×6=18, 6×3=18, 18/6=3, 18/3=6).

Inverse Operations


Like this example says, inverse operations are operations that undo each other. For example multiplication undoes division, division undoes multiplication; addition undoes subtraction, subtraction undoes addition.

Reading Comparative and Superlative Adjectives

Adjectives: describe a noun or a pronoun; tell what kind, how many, or which one; how something looks or feels

Comparative adjectives: compare two nouns

            end in -er  or  have the word more before the adjective

            Examples: shorter, taller, longer, more brown, more colorful

Superlative adjectives: compare three or more nouns

           end in -est  or  have the word most before the adjective

          Examples: shortest, tallest, longest, most brown, most colorful

Adding inflection ending -ed

Makes words past tense

Short vowel consonant: the final consonant is doubled

        Examples: tap– tapped, wrap– wrapped,

Words that end with a silent “e”: drop the e and add ed

        Examples: tape– taped, name– named

Words that end with a consonant y: change the y to an “i” and add ed

        Examples: study– studied, try– tried

Words that have a long vowel sound or end with two consonants: add -ed

        Examples: sail– sailed, travel– traveled,  land– landed
