What the Expert Says:

The term is used as means of asking students to write down equations using simple mathematical symbols (numerals, the four basic mathematical operators, equality symbol)[5]. Sometimes boxes or shapes are used to indicate unknown values. As such number sentences are used to introduce students to notions of structure and algebra prior to a more formal treatment of these concepts.

A number sentence without unknowns is equivalent to a logical proposition expressed using the notation of arithmetic.

[edit] Examples
A valid number sentence that is true: 3 + 7 = 10.

A valid number sentence that is false: 7 + 9 = 17.

A valid number sentence using a 'less than' symbol: 3 + 6 < 10.

An example from a lesson plan:

Some students will use a direct computational approach. They will carry out the addition 26 + 39 = 65, put 65 = 23 + □, and then find that □ = 42.[6] (wikipedia)

I hope this is helpful!

Hi,

My son just finished first grade and he had a lot of "number sentence" assignments.  In his class, a "number sentence" was an equation (2 + 4 = 6).  Most often they would have to read a story and write a "number sentence" about it.  ("Two ducks were floating in a pond.  Four geese were in the pond too.  How many birds were in the pond?"  and he would then have to write 2 + 4 = 6)

Hi dblga, a number sentence is usually used when trying to figure out a word problem. For example, âThere are seven cookies, but then Steve eats three cookies, how many cookies are left?â So the student will have to write out â 7-3=4â Other times the student may just be given numbers and they have to create number sentences from them. For example, âThe numbers are 2,4,6,â the child will then create number sentences â( 2+4=6),( 4+2=6),( 6-2=4),( 6-4=2)â I have provided a link below for a number sentence game for additional practice in learning number sentences, I hope this helps!

Hi dblga,

Thanks for using JustAsk!

The exact definition of a number sentence is an equation or inequality expressed using numbers or common symbols. This means that a number sentence can either be a definite equation, such as 1+2=3, or it can be an inequality, like 3 + 4 > 5.

Below, I've included a link to a fun Number Sentence Game that might make the process of learning number sentences a little more entertaining! For extra practice, you might also try browsing some of our free first grade math worksheets.

Hope this helps, and good luck!

Number sentence is a term typically used in primary level math, it is typically an equation or inequality expressed using numbers.  To form a number sentence, choose the correct operation such as addition, subtraction, multiplication or division or a comparing symbol such as = equal to, < less than or > greater than.  For example: 3+6<10.

I'm sorry, it seems that my example did not show correctly- here are other examples:  3 + 6  < 10
indicating that 3+6=9 which is less than 10
or 7+8 >12
indicating that 7+8=15 which is greater than 12 or
6+6 = 8+4
indication
6+6 =12 is equal to 8+4 which also equals 12
and so on.

a number sentence is simply an expression in numbers

eg   5-3=2  is a number sentence

a more complex example would be

3+4 - (2x5)= 17   is this true or false?

sometimes a number sentence will have a missing value-usually following the equals symbol
 4x7=

or

4x _ = 28     find the missing number

I hope this helps
