Q1Asha writes 0.05 as larger than 0.5 because it has more digits. Which first aid is best?

A Tell her that decimals with more digits are always smaller
B Give ten more worksheet comparisons without materials
C Use a tenths-hundredths place-value mat to show 0.5 and 0.05
D Move her back to only whole-number addition for a week
Explanation

Asha needs to see that five tenths is larger than five hundredths. A place-value mat makes the decimal columns visible, so her comparison stops depending on digit count.

Q2Which option is a mixed fraction?

A 3/5
B 2 1/4
C 7/4
D 0.25
Explanation

A mixed fraction has a whole number and a proper fraction, so 2 1/4 matches the definition. The other choices are a proper fraction, an improper fraction, or a decimal form, which test common confusion between forms.

Q3Which item is directly inside the verified RBSE Level 1 Mathematics fraction boundary?

A Comparison of proper fractions with same and unequal denominators
B Multiplication and division of fractions as the main Level 1 target
C Algebraic equations with fractions in two variables
D Proof of decimal expansion of irrational numbers
Explanation

The RBSE anchor used in the note lists proper fractions, comparison with same and unequal denominators, mixed fractions and addition-subtraction. Asha’s revision should begin there before moving to extra tricks or upper-grade operations.

Q4Match the error with the best first support. 1. Adds denominators. 2. Compares 0.05 and 0.5 by digit count. 3. Ignores equal parts.

A 1-strip model, 2-place-value mat, 3-paper folding
B 1-place-value mat, 2-paper folding, 3-cross-multiplication
C 1-dictation, 2-strip model, 3-mental arithmetic drill
D 1-test again, 2-mark wrong, 3-give harder numbers
Explanation

The assessment section names Birsa’s denominator-addition error, Asha’s decimal place-value error and Maria’s equal-parts need. A matching tool is better than repeating the same written question.

Q5What does the denominator tell in a simple fraction lesson?

A How many unequal pieces the teacher can see on the plate
B How many equal parts the whole has been divided into
C How many selected parts are shaded or eaten
D How many children are sitting in the group
Explanation

The core concept section separates numerator and denominator clearly. The denominator is not the number of children or selected parts; it is the count of equal parts in the whole.

7A child says that 1/2 and 2/4 are different because the numbers written in them are different. Which teacher response best builds the idea of equivalent fractions?

ATell the child to memorize that both are equal.
BSay that fractions with larger numerators are always larger.
CUse two same-size paper strips, shade 1 out of 2 equal parts on one and 2 out of 4 equal parts on the other, then place them together to compare.
DAsk the child to add the numerators and denominators of the two fractions.

8Arrange these numbers from smallest to largest: 0.4, 0.25, 0.5, 0.05.

A0.05, 0.25, 0.4, 0.5
B0.5, 0.4, 0.25, 0.05
C0.4, 0.5, 0.05, 0.25
D0.05, 0.4, 0.25, 0.5

9Consider the subtraction 6/9 - 2/9. Which option gives the correct result and the correct reason?

A4/0, because both numerators and denominators are subtracted.
B8/9, because the numerators are added.
C4/18, because only the denominators are added after subtracting the numerators.
D4/9, because only the numerators are subtracted and the denominator stays 9.

10A child says 1/8 is greater than 1/4 because 8 is greater than 4. Which response best diagnoses the child's reasoning?

AMark it wrong and immediately tell the rule.
BAsk the child to shade 1/4 and 1/8 on equal strips and explain which part is larger.
CGive five more comparison questions with the same numerator.
DAsk the child to compare 8 and 4 on a number line.

11A teacher shows a 10-square strip. Seven equal squares are shaded. Which decimal represents the shaded part?

A7.0
B0.7
C0.07
D10.7

12Which fraction is equivalent to 3/5?

A6/10
B4/6
C9/10
D3/10

13Add: 1 1/4 + 2 2/4

A3 3/8
B3 2/4
C3 3/4
D4 3/4

14On a number line from 0 to 1, the segment is divided into 5 equal parts. Where will the fraction 3/5 be placed?

AAt the second mark after 0
BAt the third mark after 0
CAt the fifth mark after 0
DAt the third mark after 1

15For introducing 3/4 in Class 4, which TLM use best keeps the idea of equal parts clear?

AShow four unequal paper pieces and count any three pieces.
BDraw only the symbol 3/4 and ask children to memorize its name.
CUse a same-size paper strip divided into four equal parts and shade three parts.
DUse three large pieces and one very small piece so that the shaded area looks big.
