Spring Math Portfolio — Show What You Know (Performance Assessment, Day 2 + Celebration)

Skills targeted
Objectives
  • Students directly compare two objects by length AND by weight using appropriate tools.
  • Students sort a collection into 2-3 categories and count each.
  • Students compose a hexagon using pattern blocks AND extend a pattern.
  • Students self-reflect on their growth across the spring term.

Lesson plan

Warm-up

3 min

'Today is Day 2 of show-what-you-know. We have FOUR stations — Measure (length + weight), Sort, Build (shapes), Pattern. You rotate every 6 minutes. Then we have a CELEBRATION at the end.'

Teacher moves
  • Walk children through each station once
  • Show the rotation timer and start it

Direct instruction

3 min

Quick review of each station: Station 1 (Measure) — compare two objects by length (cube measurement) AND by weight (balance pan). Station 2 (Sort) — sort 12 buttons into 3 categories, count each. Station 3 (Build) — fill a hexagon outline with pattern blocks in 2 different ways. Station 4 (Pattern) — extend a number pattern (10, 20, 30, __, __) and translate a color pattern to shapes.

Checks for understanding
  • Any questions before stations start?

Guided practice

24 min
Tasks
  • Station 1 (Measure, 6 minutes): compare two paper strips by length using linking cubes; compare two objects on the balance pan. Record on station sheet.
    scaffold Station sheet pre-printed with measurement vocabulary.
  • Station 2 (Sort, 6 minutes): sort 12 buttons by holes into 3 categories; count each; record on tally chart.
    scaffold Sorting mat with pre-labeled zones.
  • Station 3 (Build, 6 minutes): compose a hexagon outline in 2 different ways using pattern blocks; draw what you built.
    scaffold Hexagon outline pre-printed.
  • Station 4 (Pattern, 6 minutes): extend number pattern 10, 20, 30, __, __; translate AB color pattern to shapes.
    scaffold 100-chart available.

Station 3 has pattern blocks and hexagon outline. Station 4 has a 100-chart and pattern strip paper. A teacher with a clipboard supervises. Style: documentary, natural light.

Formative assessment

5 min
Exit ticket
  • GROWTH REFLECTION SHEET (assessment-as-learning): (1) Draw a picture of yourself doing your favorite math activity from this spring. (2) Complete: 'In the fall I could ___. Now I can ___.' (3) Rate yourself on a 3-star scale: ☆ I am starting, ☆☆ I am practicing, ☆☆☆ I am ready for first grade!
  • Share one growth point with a partner.
scoring Self-reflection rubric: 3 stars = high engagement; 2 stars = moderate; 1 star = check in. Teacher review of station sheets for skill mastery against rubric.

8.5x11 inch reflection sheet. Top section: large blank box labeled 'DRAW YOURSELF DOING MATH'. Middle section: two sentence frames 'IN THE FALL I COULD ___.' / 'NOW I CAN ___.' Bottom section: three stars to color in (☆ STARTING, ☆☆ PRACTICING, ☆☆☆ READY FOR FIRST GRADE) with sentence 'I rate myself ___ stars because ___.' Style: warm, encouraging, child-friendly. Three faces (smile, neutral, thoughtful) at top of page for emotion-check.

Closure

Moves
  • CELEBRATION: brief class chant of partners-of-10 (one final time), distribution of 'KINDERGARTEN MATHEMATICIAN' certificates, and one read-aloud of the children's favorite math book from the term.
  • Math Detective final-close: 'You started as counters. You finish as mathematicians. First grade — we are READY!'

Homework

Tasks
  • (No homework — celebration day.) Optional: tell a grown-up THREE things you learned in math this spring.

Differentiation

Scaffolds

Teacher notes

Final lesson of the spring term. Day 2 of portfolio assessment covers GM, DS, and AT (patterns) strands. Station rotation keeps energy high. The Growth Reflection Sheet is the assessment-as-learning capstone — children explicitly compare their fall-self to their spring-self. The certificate is symbolic but matters — children take it home as evidence of math identity. Save station sheets and reflection sheets in each child's portfolio; communicate with G1 teacher about portfolio handoff. Mastery scoring against the rubric (see assessments section) provides the per-skill snapshot for the parent communication at the unit's end.
