Core Skills Analysis
Math
- Grouped objects into dozens and half‑dozens, building a concrete sense of counting by 12 and 6 and reinforcing the concept of equal groups.
- Added three two‑digit numbers by aligning tens and ones columns, applying place‑value knowledge and carrying over when needed.
- Skip‑counted by 50s and used doubles to reach sums of 18, strengthening number patterns, mental‑addition strategies, and fluency with addition facts.
- Interpreted >, <, = symbols; recorded data with tally marks; measured ingredients using cups, half‑cups, tablespoons and teaspoons; and created repeating/color patterns and read clocks, integrating measurement, data, and time concepts.
Tips
Extend the learning by turning the kitchen measurements into a mini‑cook‑off where she follows a simple recipe, converting between cups, tablespoons and teaspoons while writing the amounts on a chart. Next, set up a ‘Dozen‑Shop’ game where she prices items in dozens and half‑dozens and practices making change with two‑digit addition. Introduce a number‑line walk in the backyard, marking every 50th step to cement skip‑counting by 50s, then have her place ‘double‑sum’ cards (e.g., 9+9) along the line to see how they land on 18. Finally, use a timer to practice reading analog clocks, pausing every 5 minutes and asking her to record the time in both digital and word form.
Book Recommendations
- MathStart: Adding Fractions, 1/2 + 1/2 = 1 by Steve Jenkins: A picture‑rich story that introduces half‑unit concepts and simple addition, perfect for reinforcing kitchen‑measure activities.
- Sir Cumference and the First Round Table by Catherine Bailey: A whimsical tale that weaves in counting, patterns, and basic geometry, encouraging children to see math in everyday stories.
- The Doorbell Rang by Pat Hutchins: A classic picture book that explores sharing, halving, and counting by groups, echoing the dozen and half‑dozen ideas.

Try This Next
- Worksheet: Create a two‑column chart where the left column lists three‑digit addition problems and the right column requires the child to draw the tally‑mark representation of the sum.
- Pattern Drawing Card: Provide a set of colored tiles and ask her to design a repeating color pattern, then write the rule (e.g., red‑blue‑red‑blue) and extend it for 20 tiles.
