No problem, right? Totally holds their attention.
A singular subject requires a singular verb, and a plural subject requires a
plural verb. Sometimes the verb changes its form depending on whether the
subject is singular or plural.
Rule: If the subject is singular, the present tense form of the verb usually ends in -s or -es
Example: He saves his money in a cookie jar.
Rule: If the subject is plural, do not add anything to the verb to form the present tense.
Example: They invest money for a living.
Rule: If the verb ends with a consonant and y, change the y to i and add -es to create the present tense.
Example: hurry + es = hurries
Rule: In the present tense the irregular verbs be and have change forms to agree with their subjects.
Example: Danny is responsible with money, but his friends are not. Danny has $10 but his friends have only $1.
(Oh, and by the way, they think 'singular' is spelled wrong - to them, it's a phone company!)
