Add and subtract fractions with like denominators and connect them to mixed-number thinking.
When the denominators are the same, the parts are the same size. Add or subtract the numerators while keeping the denominator unchanged.
Open one card at a time, read the text together, and use the audio button when hearing the line once helps.
fraction addition
Same denominators mean add the numerators.
Example: 2/8 + 3/8 = 5/8.
fraction subtraction
Subtract the parts because the whole is shrinking.
Example: 7/10 - 2/10 = 5/10 or 1/2.
whole from fractions
A denominator-sized number of parts makes one whole.
Example: 4/4 = 1 whole.
visual model
Models make fraction operations easier to understand.
Example: Visual thinking supports fraction accuracy.
These next steps stay in the same stage so the child does not get sent backward.
Use tenths and hundredths in practical settings like money, length, and weight.
Break a larger problem into smaller steps and decide which operation to use at each stage.
Solve practical problems about box volume, elapsed time, and angle or shape properties.
