🔢Understanding Decimals: Tenths are represented as the first digit after the decimal point (e.g., 0.1), while hundredths are represented as the second digit after the decimal point (e.g., 0.01).
    🧮Converting Tenths to Hundredths: To add tenths and hundredths, you often need to convert tenths to hundredths by multiplying both the numerator and denominator by 10. For example, $\frac{3}{10}$ = $\frac{30}{100}$.
    📊Visual Models: Using visual models like grids or number lines can help understand the values of tenths and hundredths and make addition easier. Imagine a grid divided into 100 squares. Each square represents $\frac{1}{100}$, and each row/column of 10 squares represents $\frac{1}{10}$.
    ➕Adding Fractions: When adding tenths and hundredths, ensure they have the same denominator (100). Add the numerators and keep the denominator the same.  For example: $\frac{2}{10} + \frac{15}{100} = \frac{20}{100} + \frac{15}{100} = \frac{35}{100}$.
    ✍️Simplifying Fractions: After adding, simplify the fraction if possible. For example, $\frac{50}{100}$ can be simplified to $\frac{1}{2}$.
