Two classes are collecting books. Look at how many books each class has so far:
Mrs. Smith's Class

Mr. Jones's Class
28 books
⭐
The Golden Rule: Mr. Jones's class collects more books to get close to 46, but they cannot go over 46!
1
Idea 1: Try adding an easy number!
Example: 10 more books
Draw 1 more ten rod, or make a jump of 10 on your number line:
Equation: 28 + 10 =
books
Is it ≤ 46? YES NO
2
Idea 2: Pick your own number!
Add:
books
Show your work (draw tens and ones, or jumps):
Equation: 28 +
=
books
Is it ≤ 46? YES NO

Idea 3: Try another number to get even closer!
Add:
books
Show your work below (draw base-ten blocks, an open number line, or equations):
Equation: 28 +
=
books
Is it ≤ 46? YES NO
The Grand Challenge: Find the Closest Match!
What is the absolute closest Mr. Jones's class can get without going over 46?
Show how you found the closest answer (draw your number line jumps, base-ten blocks, or counting up):
Fill in the closest possible math sentence:
28 +
= 46 books total. They could collect
more books!
Explain why this is the closest possible answer:
"If they collected just 1 more book (19 books), their total would be , which is MORE than 46!"
