1/3 + 1/4, solved three ways. Same answer every time. Pick the way that clicks for you.
🍎 For teachers and families: all three ways reach the same standard
New York State standard NY-5.NF.1:
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.
The official text then gives two worked examples; they are not copied here.

Strips and the number line show why a common denominator is needed: the parts must be the same size before they can be counted together. Any common denominator is accepted (12, 24, ...), and the answer is accepted in any equal form (6/8 or 3/4); the star message shows the simplest form. This page covers sums less than 1; mixed numbers and subtraction are in the lesson itself.
These ways are general mathematics. Goal100 wrote and drew them; nothing is copied from any publisher's program. Goal100 does not say which program your school uses: the learner picks by picture. Progress stays on this device.
