Explanation:

• Bead strings are ideal for helping to maintain student interaction in the classroom.
• If a student reads 203 as twenty-three then a teacher can use beads and strings activity.
• This activity is great for emergent learners during maths lessons.
• They are perfect for both group as well as individual led work, encouraging problem-solving, number exploration, and familiarity with multiples of ten.

Beads and Strings activity:

• Bead strings are used for visualizing numbers with a moveable object.
• A teacher can hide or cover certain parts of a bead string so the students find it easier to count each bead by counting it one by one. 
• We can Use bag tags to label the beginning and end of the string as 0 and 100.
• A 10 bead string contains five white and five red beads.

​Recognizing the number 203:

• Split the beads to represent the numbers 20 & 23, then ask the pupil what number it represents.
• From the beads below, you could prompt students to count all the green beads, and write down the number it represents.
• Then by doing this activity a pupil comes to know that there is a difference between 23 & 203. So 

So Misconception of Recognising a Number can be cleared by Beads and Strings activity.  So Option 3 is the correct answer.

Other Uses of beads and strings activity:

• Recognizing numbers
• Place value
• Estimation skills
• Large numbers
• Addition and subtraction
