In this video, Mr. Tom introduces the concept of using tens frames for subtraction, a tool that helps visualize subtraction problems up to 20. The video explains what tens frames are and demonstrates how to use them with examples like 7 minus 3 and 13 minus 6. The session concludes with a review of the key points and an invitation to explore more math tools in future sessions.

What is the primary use of tens frames as introduced in the video?

• To measure length

• To add and subtract numbers up to 20

• To divide numbers

• To multiply numbers

How many equal parts is a tens frame divided into?

• Five

• Ten

• Fifteen

• Twenty

When using tens frames, how many frames are typically used at a time?

• Two

• One

• Four

• Three

In the example of seven minus three, how many counters are left after subtraction?

• Five

• Four

• Three

• Two

What is the first step in solving a subtraction problem using tens frames?

• Divide the frame into more parts

• Add more counters

• Remove all counters

• Fill the frame with the initial number of counters

What is the purpose of counting back when using tens frames for subtraction?

• To divide the counters equally

• To find the total number of counters

• To remove the correct number of counters

• To add more counters

What is the result of the subtraction problem: seven minus three?

• Two

• Three

• Four

• Five

What is the result of the subtraction problem: thirteen minus six?

• Five

• Six

• Seven

• Eight

What is a shortcut mentioned for counting the remaining counters in a tens frame?

• Using multiplication

• Counting by twos

• Using addition

• Counting by fives and adding the rest

What should you do after filling the tens frame with the initial number of counters?

• Divide the counters into groups

• Remove the counters equal to the number being subtracted

• Add more counters

• Count the total counters
