Being read to is a magical experience for kids, and is a crucial stepping stone for language learning. GLEN Books provides a collection of illustrated children’s story books in English and Spanish, narrated with synchronized text-highlight and the book pages being “turned” on the screen. The stories include popular children's classics, including adaptations of Aesop's fables and Indian folk tales, as well as original stories. Kids don’t need to know how to read in order to enjoy these beautifully illustrated stories by our expert narrators, but the audio-synced text highlighting provides a constant invitation to step into reading. Beginning readers can practice and develop their skills by turning off the narration, or by playing audio for selected phrases in the text. GLEN Books can be used to strengthen language skills for children at homes or in informal preschool environments, as well as a complement to in-class activities in Kindergarten-1st grade school settings. The auto-narration feature allows parents and caregivers to enjoy story-time with their kids regardless of their own level of literacy. Skilled teachers can craft a rich set of reading, comprehension and bilingual activities around GLEN Books. KEY FEATURES * Children’s stories in English and Spanish * Designed to engage kids of all ages with rich illustrations and warm narration * Audio-synced text highlighting is an invitation to reading * Flexible auto-narration: on, off, and phrase-by-phrase * Adapted children’s classics as well as original stories GLEN Books is developed by GLEN World, a nonprofit organization developing research-based learning apps to scale early English literacy.

ExamReady Math is a focused, standards-aligned practice app for Grade 4 students preparing for the New York State math exam. No ads. No data collection. No subscriptions. Just honest practice that actually understands kids' work. WHY IT'S DIFFERENT Most test-prep apps grade "show your work" by keyword-matching kids' explanations. That fails whenever a child gets the right answer in different words. ExamReady uses real multiple-choice reasoning for the "why" steps and numeric equivalence for answers — so 15/8, 1 7/8, and 1.875 all count as the same answer. Kids see exactly what we expected when they miss. VISUAL FRACTIONS YOU CAN SEE Compare 3/5 and 4/10 with shaded bars and a 1/2 benchmark line, not just abstract symbols. The fraction bars use the same strategies the NY State exam expects: benchmark fractions, common denominators, and visual area models. STEP-BY-STEP SCAFFOLDS Multi-credit "Show Your Work" problems break down into clear numeric steps and multiple-choice reasoning. Kids build the full answer one piece at a time, the way Grade 4 teachers actually teach it. FULL TIMED MOCK EXAM A real two-session simulation — Session 1 (15 MC, 25 min) and Session 2 (10 MC + 3 Show-Your-Work, 30 min) with a break screen between. Kids see their score at the end with a per-session and per-domain breakdown. No immediate feedback during the exam, because that's how the real test feels. APPLE PENCIL SCRATCHPAD Pull up a PencilKit canvas on any question to work the problem out by hand. Drawings persist per-question within a session. Works with finger or Apple Pencil. iPAD-OPTIMIZED Two-pane layouts on iPad for "Show Your Work" questions, adaptive fraction bars, and a math keypad that floats with the keyboard. 56 QUESTIONS · 16 DOMAINS · ALL NY STATE STANDARDS Fraction equivalence and comparison (4.NF.1, 4.NF.2), fraction operations (4.NF.3, 4.NF.4), decimals and fractions (4.NF.5–7), place value to 1,000,000 (4.NBT.1–3), multi-digit arithmetic (4.NBT.4–6), multiplicative comparisons (4.OA.1–2), multi-step word problems (4.OA.3), factors and multiples (4.OA.4), number patterns (4.OA.5), measurement conversions (4.MD.1–2), area and perimeter (4.MD.3), line plots (4.MD.4), angles (4.MD.5–7), lines and rays (4.G.1), shape classification (4.G.2), and lines of symmetry (4.G.3). PROGRESS TRACKING FOR PARENTS The Progress tab shows your child's mastery across every domain, their practice streak, and which topics need the most work — so you can focus at-home review time where it helps most. PRIVACY BY DESIGN The app runs 100% offline. Nothing is transmitted anywhere. Progress, scratchpad drawings, and exam history are stored only on your device. No third-party analytics, no advertising SDKs, no account required. Made for ages 9–11. Designed for kids; transparent to parents. ExamReady Math is not affiliated with the New York State Education Department.
