Question 2.
Write the number as tens and ones in the place value chart, or use the place value chart to write the number.
a. 32 Answer: 32 if formed using 3 tens and 2 ones
Where
3 tens is equals to 30
And 2 ones is equals to 2
By adding 3 tens and 2 ones we get 32
30+2=32 b. 19 Answer:19 if formed using 1 tens and 9 ones
Where
1 tens is equals to 10
And 9 ones is equals to 9
By adding 1 tens and 9 ones we get 19
10+9=19 c. ________ Given value chart has 2 in tens place and 6 in ones place
That is the value chart shows 2 tens and 6 ones
where
2 tens is equals to 20
And 6 ones is eual to 6
By adding 20 with 6 we get 26
20+6=26 d. _________ Given value chart has 1 in tens place and 5 in ones place
That is the value chart shows 1 tens and 5 ones
where
1 tens is equals to 10
And 5 ones is eual to 5
By adding 10 with 5 we get 15
10+5=15 Question 3.

0            10            20          30              40 b. Shade in the tens or the ones on the place value charts below to show which digit you looked at to help you put the pair of numbers in order from least to greatest.  Question 4.
Complete each sentence.
a. 39 is _________ tens and _________ ones.
b. 40 = _________ tens _________ ones.
c. 2 tens and 3 ones is the same as _________ ones.
a. 39 is 3 tens and 9 ones.
3 tens is equal to 30
And 9 ones is equal to 9
By adding 30 with 9 we get 39
30+9=39
b. 40 = 4 tens 0 ones.
4 tens is equal to 40
And 0 ones is equal to 0
By adding 40 with 0 we get 40
40+0=40
c. 2 tens and 3 ones is the same as 23 ones.

b. 30 3
c. 23 32
d. 19 21
a. 3 tens 5 ones 2 tens 8 ones

b. 30 3
c. 23 32

d. 19 21

Question 8.
Erik thinks 32 is greater than 19. Is he correct? Draw and write about tens and ones to explain your thinking.
32 is greatr than 19
As 32 has 3 tens and 2 ones
And 19 has 1 tensand 9 ones
32 19 Question 9.
Find the mystery numbers. Use the arrow way to explain how you know.
a. 10 more than 19 is _______. Adding one tens to one tens and 9 ones.
19+10=29
19= one tens and 9 ones
29= two tens and 9 ones

b. 10 less than 19 is _______. Removing one tens from one tens and 9 ones.
19-10=9
19= one tens and 9 ones
9=Zero tens and 9 ones

c. 1 more than 19 is ________. Adding one to one tens and 9 ones.
19+1=20
19= one tens and 9 ones
20 = two tens

d. 1 less than 19 is ________. Removing one from one tens and 9 ones.
19-1=18
19= one tens and 9 ones
18 = one tens and 8 ones

Question 10.
Beth said 30 – 20 is the same as 3 tens – 2 tens. Is she correct? Explain your thinking.
Removing 20 from 30 we get 10

2 tens = 20
so both are same

Question 11.
Solve for each unknown number. Use the space provided to draw quick tens, a number bond, or the arrow way to show your work.
a. 30 + 6 = ___________
b. 3 tens — _______________ = 1 ten
c. 11 + 10 = ___________
d. 40 — 30 = ___________
e. 17 + 20 = ___________
f. 20 + _____ = 40
g. 15 + _____ = 35
h. 2 tens + 1 ten 2 ones = _________________
a. 30 + 6 = 36
Adding of 3 tens with 6 ones =36
b. 3 tens — 2tens = 1 ten
Removing 20 from 30 makes 10
30-20=10
c. 11 + 10 = 21
