Victoria is subtracting from
nine. Write the missing sentence. Nine take away one equals
eight. Nine take away two equals
seven. Nine take away three equals
six. What? Nine take away five equals
four. Nine take away six equals
three. Nine take away seven equals
two. And nine take away eight equals
one.
In this question, we need to
write the subtraction sentence which matches this picture. We know our subtraction
sentence begins with the number nine because all of the subtraction sentences
begin with the number nine because there are nine counters in the ten frame to
start with. We also know that this is a
subtraction sentence, but we don’t know how many we need to subtract. Let’s use the picture to help
us. We’re subtracting one, two,
three, four.
We can also use the subtraction
sentences to help. The number that we subtract
each time increases by one. One, two, three, four. Now, all we need to do to
complete our number sentence is write the number of counters that are left. We could use the subtraction
sentences to help again. We’re taking away one more each
time. The numbers are going down by
one each time. Eight, seven, six, five. Nine subtract four equals
five. We found the missing
sentence. We use the pictures and the
subtraction sentences to help.
